Why does the VAZ 2110 stove heat poorly?

Unfortunately, most VAZ 2110 car owners notice that the stove does not heat well, only in winter, when it is turned on after a long period of inactivity.

Many people remember that the VAZ-2110 car was at one time one of the most popular and sold in Russia.

It's easy to explain at an affordable price, efficiency, comparative reliability and low cost of maintenance.

At one time, the 2110 model became the first step towards creating European-style cars.

Naturally, there were many “sins” left for the VAZ-2110, which led to a large portion of criticism, both from experts and from the actual owners of this model.

Many car enthusiasts complain that the VAZ 2110 stove does not heat well. But if you know some of the nuances of system maintenance, this problem can be easily solved.

Briefly about the design

It is important to know that the heater of a VAZ-2110 car consists of two different elements.

1. Directly to the heater.

This unit is located under the hood of the car. Its task is to prepare the air before entering the cabin vehicle, that is, control of feed speed, temperature, and so on.

2. Air distributor.

This system is located directly inside the car and is located on the instrument panel.

See the general structure of the VAZ 2110 stove below.

Malfunctions in the heating system

Now let's discuss why the VAZ 2110 stove may heat poorly.

There are several main reasons for this :

• firstly, the seal in the radiator of the device was broken, which led to a leak;
• secondly, there is no way to change the temperature regime of the heater;
• thirdly, elements of the system such as a gearmotor or damper have failed;
• fourthly, there were malfunctions in the operation of the automatic control system (the unit responsible for controlling the heating system);
• fifthly, the temperature sensor, which is mounted in the ceiling of the car, is faulty.

Winter has come, and many car owners are beginning to notice that their car's heater is not heating well.

This is the wrong approach. It is necessary to prepare the “sleigh” in the summer - isn’t that what folk wisdom says?

Therefore, it is advisable to carry out diagnostics while still warm and, if malfunctions occur, correct them immediately.

How to act if the VAZ 2110 stove does not heat well, read on.

So, we have dealt with the causes of malfunctions of the VAZ 2110 stove, now let’s move on directly to troubleshooting the problems.

Adjustment problems temperature regime– one of the most common causes of malfunction. In most cases, this is caused by a failure of the control unit or damper.

How to proceed in this case?

Check functionality temperature sensor(it is located on the ceiling, near the interior lamp).

It is because of its malfunction that the required command may not reach the damper.

Diagnosing a sensor malfunction is simple - move the control knob to one extreme position, and therefore the other. In this case, it is necessary to monitor whether the temperature of the outgoing air changes.

There can be two options here - the temperature does not change at all, or the air begins to warm up only when the handle is in the extreme (maximum) position.

In the first case, repairing the VAZ 2110 stove by replacing the sensor alone will not cost you - you need to look for another reason.

In the second case, we can confidently talk about the failure of the controller itself.

Failure of the gear motor.

If, when the heating is turned on, only cold air, then there are obvious problems with the stove.

In 9 out of 10 cases, the cause of such a malfunction is the failure of the gearmotor. Typically, replacing this element allows the system to return to full functionality.

The sequence of actions will be like this :

1. Remove the windshield wipers;
2. Remove the frill (to do this, you need to unscrew three screws);
3. Disconnect the wires from the gearmotor;
4. Remove the old one, install and connect the new device.

For greater convenience, it is better to hire a partner as an assistant - he will adjust the air from the cabin.

The procedure for removing the gearmotor of the VAZ 2110 stove .

Heater failure.

Sometimes the cause of a malfunction of the VAZ 2110 stove can be the heater itself. To verify this (or refute the assumption), it is necessary to dismantle the main deflector.

This is easy to do - just bend the special fasteners and move the damper (you can climb up to it from the side engine compartment).

If the radiator breaks down and needs to be replaced, you will have to disassemble the entire stove (if desired this work you can do it yourself).

Poor quality of air heating by the stove.

If you are not satisfied with the VAZ 2110 stove in terms of the speed and quality of air heating, then you should take a few simple steps:

• Firstly . do not be greedy with money to buy a high-quality aluminum damper (it is better to throw away the old “piece of plastic” right away). Such a replacement eliminates the curvature of the damper when switching and, accordingly, helps conserve heat;

• Secondly . install a new heater (factory type is the same high quality). The most preferable option is to purchase heaters from a VAZ-2112-1 or 2112-2. But there are some disadvantages here too. The first type does not have a cleaning filter, and the second type does not have a recirculation function. Each of the filters described above can easily “go away” 15 thousand kilometers;
• Thirdly . it won’t hurt to spend money on installation preheaters or many people call such a device an antifreeze heater. Their task is to preheat the interior and engine.

Insufficient airflow in the area of ​​the side windows and feet.

According to the complaints of many car enthusiasts, the VAZ 2110 stove does not warm up the legs and windows enough. In such a situation, the only way out is to improve the air channels inside the car.

You must act in the following sequence:

• 1. Make sure the stove is working. Only after this does it make sense to modernize the system.
• 2. Dismantle the panels completely and disassemble them into small components.

• 3. If there are cracks (slots) in the panel, seal them or install a new hose. But in most cases, the first option is quite sufficient.

• 4. Inspect the top and bottom of the panel carefully. If there are cracks, they must be carefully treated with anti-creak. Try to do everything efficiently, because you won’t have time to return to this work later. The fastening points and holes must also be carefully taped.
• 5. Remove the damper along with the factory seal. Now carefully glue the valve using modelin and process the existing gaps (including on the driver’s side).
• 6. Inspect the air ducts that go to the feet. If there are cracks, seal them.
• 7. Remove the factory air distributor, insert corrugated tubes into the holes and seal everything with foam for security. Special attention must be given to the pipe - it must have a thickness of at least four centimeters in diameter.

• 8. As a result, you get three tubes, one of which goes back to the passengers, and the other two to the driver and front passenger. All that remains is to put everything back in place.

Secrets of using a heater

In order for the VAZ 2110 stove to work as long as possible, you need to follow a few simple secrets:

1. Look at how the carpets are positioned under your feet to see if they are blocking the outlet of hot air. If the nozzles are blocked for any reason, they must be raised.
2. If you have an air conditioner in your car, it is advisable to turn it on when it is very damp outside.
3. It is advisable to use both heating positions - on the glass and on the feet. The first position is suitable for quickly drying the windshield, and the second for heating the feet.
4. Before turning on the heater, remove all excess from the glass.

conclusions

Remember that the efficiency of the stove and not only the VAZ 2110 depends on you. Of course, the manufacturer has not provided for everything in this matter, but you have the hands, knowledge and desire to do everything perfectly.

By spending 1-2 hours of your time, you will 100% prepare your car for winter. Good luck.

If the heater in a VAZ car blows poorly on the sides or the warm flow does not reach the feet, then this is not always a sign of a malfunction. The stove in domestic cars most often already comes with defects. Other examples are constant fogging of windows during rain or lack of heat for rear passengers. We can solve these problems with the help of modifications to the VAZ 2110 heater. But to understand why the heater does not work well, you need to familiarize yourself with its design.

The stove in the VAZ 2110 is made of a separate system:

• The first element is a heating unit that heats the incoming “outboard” air. This unit is located under the hood. Its functions are air temperature control and flow rate.
• The second element here is the air distributor. Warm air blows into the interior of the VAZ 2110 through air blowers. The air distributor elements are located on the car dashboard.

If you are going to change the heater, then you need to find the original model, that is, for the VAZ 2110. Extra units will not be effective, since for the “ten” a special stove “2110-01” was produced, the device of which contains an evaporator.

Basic faults

The driver's legs often suffer in domestic cars. Because of this defect, not only does the driver freeze, but the windows also fog up, which is also not very pleasant. This directly affects the control of the car. Why does the heater blow badly into your feet? It's all about the plastic block for distributing warm air, which among motorists is called a “herringbone”. Initially, this block has small gaps. To upgrade, we need to make sure that the stove is in full working order, that is, it is blowing warm air.

The repair is carried out as follows:

1. We dismantle the torpedo and disassemble it.
2. We get to the blower pipes. You can already solve the poor airflow of the side windows: seal all the cracks that are present on the panel, or install a new corrugated hose.
3. It will be great if you install a corrugated hose and seal the panel.
4. It is best to cover the cracks with Anti-creak. You need to go through all the holes with fasteners.

   Now you can upgrade the stove damper. When assembling a VAZ 2110, the damper is unreliably pressed against the panel body, as a result - some of the heat is lost and remains in dashboard, but the stove does not heat 100%.

5. To solve the problem when the stove does not blow well into your feet, you need to completely dismantle the damper and remove the standard seal. All cracks and the valve itself should be treated with Madeleine. This operation will create an ideal "path" for the heated air. On the body of the VAZ 2110 we need to install bitoplast-10, which will replace the standard sponge. It needs to be glued in several layers.
6. After this, your feet should receive more warmth. Another problem is the loss of heat on the way to the glass from the driver's seat. This gap is removed with polyurethane foam; as a bonus, there is no creaking.
7. Feet can freeze not only for the driver, but also for his passengers. To prevent this from happening, it is necessary to modernize the air ducts. Heat is distributed throughout the cabin by a block that usually has a large gap. You can seal it using a corrugated tube. After this, the stove heats and blows more intensely.
8. You can also remove the standard air distributor. Instead, you need to place high-quality corrugations in all holes. They are attached to the panel using foam. The diameter of each pipe must be exactly 40 millimeters.
9. As a result, when proper operation, we will have the following corrugations: one warms the driver’s feet, the second and third warm the passengers’ feet.

Alternative options for upgrading the stove

The first method is to dismantle standard air ducts. They come from the main tunnel under back row. Due to the hard plastic, the warm flow does not reach the rear passengers. By installing more modern air ducts, we will get a more pleasant result. Some drivers prefer to dismantle them altogether in order to hot air went directly - this is also a good option, but the temperature may be too high.

The third option is suitable for those VAZ 2110 owners who very rarely carry rear passengers. It consists of completely blocking the flow to the rear of the car. This can be done suitable material. For example, polystyrene foam. The main thing is that the material can withstand high temperatures. The hole can be closed at the outlet of the distribution block. The result is a powerful flow to the feet of the driver and front passenger.

An excellent option for solving a heating problem is to replace the standard 5-hole thermostat with a 6-hole one. The effect will be noticeable: after turning the handle one and a half turns, the cabin thermometer on-board computer will not show less than 90 degrees. The temperature remains stable, and the stove heats better.

The fourth option is to install a plug for the central deflector. This part will practically block the path of air to the deflector, so the flow will be directed to heating the entire cabin, including the side windows, which are constantly frozen in winter.

Useful information on using the heater

The above methods help improve interior heating. But it wouldn’t hurt for motorists to familiarize themselves with the operating rules of the stove and adjacent systems. This will help keep the heater in working condition:

• If you have installed an air conditioner in a VAZ 2110, then it is best to run it in wet weather.
• In cold weather, it is most effective to use two positions of the heater: “all on your feet” - when starting to drive, “all on the glass” - a minute before the car starts.
• The nozzles should not be blocked by anything. Motorists often place carpets on them, which absorb heat. To avoid this, you need to raise the nozzles above some kind of lining. Then nothing will disturb them when the blower is running.
• Before starting the stove in the cold season, it is necessary to clean all the glass from moisture or dirt.

Cold air from the stove

Throttle lever cable

In addition to a leaky design, there may be other problems with the stove. For example, the heater is not working at full capacity, the air blowers are blowing cold or barely warm air. The stove works this way because a bit of a stretch damper control cable. We need to solve this problem by making several turns of the cable on the control lever, which is located on the heater body. The housing is located near the gas pedal.

Why does the stove work poorly and blow cold air because of this cable? The fact is that each joint of the air ducts and the damper is covered with foam rubber. Because of this material, the control lever requires a lot of force to compress the flaps. As a result, a gap of 2-4 mm appears. The damper that takes in “fresh air” through the radiator or from the street does not close well. After a few millimeters, the outside air flows directly into the side and top blowers. At speed and with the fan running, the air does not have time to heat up, so the stove operates in “summer” mode and does not heat the interior well.

Formation of air jams

If at operating temperature antifreeze and cold air is blowing from the deflectors when the tap is open, then most likely the radiator is not working properly - there are air pockets in it. The problem is solved quite simply: the VAZ 2110 is installed so that the front wheels are higher than the rear ones. That is, to a suitable height where the engine runs at normal mode. Next, we need to fully open the tap and press the gas pedal. The engine runs for about 5 minutes - during this time we sometimes need to press the gas pedal. After this, everything needs to be returned to its original position.

Faucet

Malfunctions may be due to the faucet, which often leaks. You can check how it works manually. This element is located under the hood next to the heating element. To eliminate malfunctions when a faucet leak is detected, you just need to replace it. Some motorists decide to simply remove the tap from the VAZ 2110 system, since the stove works and blows without it. But by removing it, we will not be able to control the temperature of the antifreeze.

This question worries many car enthusiasts, especially when the first severe frost and dank damp weather clearly remind us of the coming of winter. I also faced the same problem. The heater in my car either didn’t heat up at all or only warmed up very poorly. Well, when instead of the expected warmth cold air blew out of it, my patience ran out. I decided that I needed to get rid of this problem as soon as possible, otherwise severe frost You won't get far in a car like this. How did I manage to repair the stove? Very simple. The accumulated knowledge plus a little experience, which I now share with you. I hope that my recommendations will help you repair your heater and avoid freezing in winter. There may be several reasons why the VAZ 2110, 2112, 2114 stove does not work. They all depend on various factors. Let's look at them in more detail: ➤ Lack of coolant in the engine cooling system. ➤ Malfunction of the heater core. ➤ Faulty cabin filter. When the VAZ 2110 heater does not work due to lack of antifreeze, it is very easy to fix the problem. Just check the coolant level in expansion tank. A radiator malfunction can be determined by its condition. Make sure it's hot. If not, then it could be because air lock. Eliminating it is also not difficult. Drive the front wheels onto some bump and let the car run for a few minutes at medium speed. Be sure to check if the radiator is leaking. Perhaps this will be the reason for the stove failure. Is your car's heater blowing weakly? Replace the cabin filter. I'll tell you one little secret. To ensure that the cabin filter lasts as long as possible, install protection on the air intake.

Solution options

Please note that the stove may not work even if the radiator is working. In this case, the reason should be sought in: ➤ problems with the controller or micromotor gearbox; ➤ interior air sensor on the ceiling; ➤ shaft position sensor; ➤ heater damper. Now let's take a closer look at what problems can arise with the heater if the radiator is working. If the controller malfunctions, the easiest way to fix the stove malfunction is to replace old part and test it in action. The whole job will take you no more than five minutes. If the micromotor-gearbox breaks down, you will have to tinker a little. Here it is necessary to remove the engine soundproofing shield and the frill.

Cold air blows from the stove

If the VAZ 2112 stove stops working and cold air is blowing from it, then perhaps the breakdown lies in faulty sensor salon on the ceiling. Now I will explain the principle of operation. When the sensor is disconnected, the micromotor reducer receives a signal different from the temperature in the stove. This is why the fan stops working in high-speed “A” mode. If the damper moves only in the extreme positions, given that the temperature sensor is disabled, there may be two reasons for the malfunction: 1. Controller temperature sensor malfunction. 2. Micromotor sensor malfunction.

The failure may have occurred due to the fan. It is installed on the temperature sensor. Check if it rotates at the MIN and MAX positions. To do this, simply apply 12 V to the terminals. How to check the controller? To do this, turn on the ignition. Rotate the temperature knob and measure the voltage on the long connector. This will be the pink and brown wires.

If your vehicle has a pre-2001 controller, the voltage should drop after approximately 13 seconds. Maybe a little less or more. The reduction occurs in the min position. In the max position, the voltage is supplied constantly. If the controller is a new model, then after 13 seconds of operation in both modes it will simply turn off. If the voltage remains unchanged at the output, then this part is faulty.

Thermostat

Most probable cause The reason why the VAZ-2114 stove does not work is a faulty thermostat. If this part is in an inoperative state, the system will constantly drive antifreeze only in a large circle, bypassing the small one. The solution to this problem will be to install a new thermostat, since repairing the old one is time-consuming and pointless.

water pump

It also happens that the pump is unable to create required pressure in system. This happens when Idling The heater does not heat up, but functions only at speed. Such signs may indicate a low level of coolant in the system. Most often, motorists install an aluminum pump instead of a standard one. Recently, a lot of fakes have appeared in stores, so be very careful when choosing. To be sure, ask the seller for the certificate included with this batch of products. By the way, some craftsmen install an additional electric pump from a GAZelle.

The stove fan is not working - what should I do?

You can understand that the fan does not turn on as follows. First, we start the engine and turn on the heater. If the stove stops making noise, as it did before, then this part is faulty.

Circuit breakers

Most often, the fan does not work due to blown fuses. 14 Ladas are equipped with 30-amp F7 fuses. It is located right behind the stove.

Ignition relay

If the stove “glitches” from time to time (it turns on only when the engine is warm), then the problem is in the ignition relay. It also happens that the fan does not work due to poor contact in mounting block. Oxidized or bad contact along with fuses, this is a very common problem when operating a heater. Here we need to move the block of wires that go to the block a little or check the quality of the contacts. The fan also breaks through the resistor. This is easy to understand - the stove will turn on only in the 3rd position of the lever. In this case, we change the additional resistor completely. So, we found out why the VAZ-2114 stove does not work.

Damper

The reason why the stove on a VAZ 2114 with an injector does not work may be a faulty damper. The heater has two dampers - upper and lower. The upper one controls the flow of cold air, and the lower one controls the flow of hot air. This problem can be easily fixed. In old-style stoves, the damper is made of plastic. It has foam seals. In new heaters, the dampers are metal and have rubber seals.

If, when you move the damper, you hear a rumble and cold air blows from the stove, then the damper may be broken or its drive has failed. If there are cracks or splits on the plastic flap, they can be glued together with dichloroethane. The metal flap is quite difficult to break, but it can easily jam. It often gets stuck due to rust. If this was the problem, I would advise you to paint it. This will solve the problem. With this I finish the description of everyone possible options. I am the owner of a dozen and here I described in detail my actions during the last stove breakdown. She took a lot of patience from me. But I feel sorry for the swallow. And I want to ride in comfort in winter. I hope my advice will help you troubleshoot all problems.

A car's heating system is an essential element for our harsh winters. The VAZ 2110 stove allows you to heat the interior well enough to avoid freezing. As practice shows, the reliability of heating domestic cars cannot fully satisfy the requirements of motorists.

She refuses at the most inopportune moment, when it’s cold outside. The VAZ 2110 stove is one of these devices, and therefore the ability to repair it yourself helps in a difficult situation.

Design Features

The VAZ heating system consists of the heat source itself (stove), a heat distribution system throughout the cabin and a control system. The heating and heat distribution system is combined with the interior ventilation system. The heat flow is controlled by an air damper (in older designs a faucet was used). The air supplied to the cabin is heated by passing through the radiator of the VAZ 2110 stove and distributed through the distribution system. Most of the flow is aimed at Windshield And side windows , through deflectors equipped with dampers, as well as into the center of the cabin. Another flow is directed to the feet of the driver and the passenger sitting next to him (through two pairs of deflectors located at the level of the floor and the level of the person’s knees), as well as through a tunnel on the floor and two air vents under the front seats to back seat

, at floor level. The VAZ stove fan provides three modes: low and medium speed and automatic speed selection (based on a signal from the control unit). The electric motor of the furnace fan is commutator, direct current . Current consumption at highest speed rotation - 14 A. Setting the speed mode of the electric motor is done by changing its connection to the car battery, directly ( maximum speed

) or through additional resistance. This resistor has a variable resistance of 0.23 Ohm and 0.82 Ohm. If the greatest resistance is connected to the circuit, then the fan rotates at low speed, and if less (0.23 Ohm) - then at average speed

. It is not recommended to remove the fan blades from the motor shaft: this may lead to imbalance. The electric motor cannot be repaired (except for cleaning the commutator contacts); if it fails, it is advisable to replace it along with the fan blades.

Block responsible for temperature The VAZ heater radiator is located below the dashboard and has plastic casing . It contains two plastic tanks (one of them, the left one, has a fitting for removing steam) and two rows with plates. Depending on how the dampers are located, a variable flow of intake air is passed through the radiator (in the extreme positions of the dampers all the air passes or does not pass at all), and the rest of the air is directed to the air vents and bypasses the radiator. The VAZ 2110 stove of the new model is controlled by signals coming from the electronic unit.

The unit receives information about the temperature in the cabin from a sensor located on the ceiling and equipped with a microfan. If necessary, the unit can operate a micromotor that controls the heater dampers. The electric micromotor has a heater damper position sensor (ring resistor).

Information from this sensor is sent to the control unit, which turns off the micromotor if the damper reaches the specified position. The heating system of the new VAZ model has auto mode(position “A”), in which the control unit provides, in addition to monitoring the engine gearbox, also control of fan rotation.

Reasons for repairs and troubleshooting

Typically, stove malfunctions are detected at the onset of the heating season, although prevention should be carried out in the warm season.

1. With the onset of winter, drivers begin to notice that the heating system of the VAZ 2110 does not work well or does not want to work at all. There are several types of malfunctions that will require stove repair:
2. The heater temperature cannot be adjusted.
3. Malfunction of dampers or gearbox.
4. Fluid leak in the radiator.
5. Damage to the ceiling temperature sensor.

Failure of the control unit.

• Often the VAZ 2110 heater does not heat well due to its radiator. Therefore, you need to check whether the radiator is hot. If necessary, it is replaced. Difficulties with heating may occur due to a lack of fluid in the car’s engine cooling system. First of all, you should measure the fluid level. To check the condition of the VAZ stove, you will have to remove the central deflectors. To do this, the antennae are bent and the flap is moved. Installing, replacing or upgrading a VAZ stove will require the use of tools such as:
• screwdriver;
• pliers;
• tweezers;
• a set of socket and wrenches;
• scissors;
• hammer;
• mallet;
• chisel;

When the temperature in the cabin cannot be controlled, the reasons may be abnormalities in the operation of the control unit or a malfunction of the damper. If the stove controller is to blame, then the command to extend the damper element does not pass. You should immediately check the temperature sensor located on the ceiling.

The test can be carried out by repeatedly changing the position of the temperature setting lever. Warming up of the air flow can be analyzed by the tactile method - by determining the performance of the sensor in the extreme position of the handle.

To check the stove itself, you will have to remove the central deflectors. The damper is accessible through the engine compartment. Modernizing the VAZ stove in this case means replacing the old damper with an aluminum one instead of a plastic one. The greatest amount of effort will be required when the stove radiator needs to be replaced, since the entire VAZ heating system must be removed.

If the fan produces only cold air, it can be assumed that the stove is faulty; Moreover, with a 90% probability the gear motor is to blame, and only replacing it will help. The VAZ heating system is repaired in the following order:

1. Wipers are dismantled.
2. Jabot steps aside.
3. The three mounting screws are unscrewed.
4. The wires are moving away.
5. The old gearbox is removed and a new one is installed.
6. Reassembly is carried out in reverse order.

Problems with a poorly functioning heater occur not only on domestic “classics”, but also on more modern cars. VAZ-2110 is no exception. In practice, it turns out that in the summer, if you turn on the stove, it will be very hot, but in the winter, on the contrary, there is minimal use from it. However, it is difficult to say why this happens, so it is necessary to consider several relevant reasons and try to eliminate them. Let's figure out why the VAZ-2110 stove does not heat well and how to deal with it.

A little about the design

The VAZ-2110 model, which is as close as possible to European cars, has many flaws, especially with regard to the heater. In our case, it is separate and consists of several elements. The first one is the heater, it is located under the hood. Its task is to prepare the air that will be supplied to the cabin. This refers to speed and temperature. The second element is located in the cabin, and this is the air distributor. If your VAZ-2110 stove (16 valves) does not heat well, then the first thing you need to do is understand which of the two units is not working correctly. Everything is quite simple here. Now you will understand why exactly.

If you do not have the ability to switch fan speeds, and it is in the heater, then it is logical to conclude that it is yours that is faulty. Of course, the issue may be in electronics, but this is very rare case. By the way, it is very important to understand the principle of operation of the stove. It consists of setting the temperature, which, using a special sensor, is compared with the one currently in the cabin. If the difference is significant, more than 2-3 degrees Celsius, then the gear motor controls the dampers, opening or closing them. If the temperature difference is more than 5 degrees, then the second fan speed is turned on, if less, then the first. Warm or cold air enters through the channels. So it goes to the side front windows, the windshield, to the feet and, directly, to the passengers. A very common reason is when the VAZ-21103 stove does not heat your feet well, but the windows blow normally. The reason may be clogged air ducts. We'll figure out how to clean them a little later.

How to remake the stove on a VAZ-2110?

If you are fundamentally dissatisfied with the operation of the heater on your car, then you can modify it to suit your needs without any problems. If you are faced with the problem of insufficient airflow or fogging of windows in rainy weather, then you need to take action. Firstly, you should make sure that the heater is in good working order and is working normally; if not, then it needs to be repaired and only then proceed with active actions. The main reason why little air flows to the side windows is that most of the flow is lost in the gap. Accordingly, you need to disassemble the entire panel into parts and use foam to prevent air leakage. This is quite easy to do. Sometimes it makes sense to lay corrugation, but in practice this does not always work. IN best case scenario There you can only warm the feet of the front passengers.

Please also note that the airflow for the rear passengers’ feet also needs to be improved. But before you remake the stove on the VAZ-2110, you need to take care of the driver’s seat. Here you will be dealing with the so-called “herringbone”. Just in time in this case It is advisable to use corrugations. Firstly, it will give the desired effect, and secondly, it takes up much less space of that very “Christmas tree”. It is desirable that the tube be no more than 40 millimeters in diameter, and if long length smooth inside. Otherwise, as air passes through it, it may whistle, which is not very pleasant.

Modification of damper and airflow

Many drivers may have encountered the problem that in very cold weather there is no way to regulate the uniform supply of warm air in all directions. So it turns out that either the side windows are covered with ice, or the legs freeze. For example, if the VAZ-21103 stove does not heat well, then the problem is obviously in the dampers. So, on vehicles that were produced after 2003, there is no such problem, but on those that came off the assembly line before, you will have to work with this. There is nothing complicated here; you will need to cut out the edges of the damper with a regular metal file (you don’t need to touch the windshield damper). You can also saw off a little bit from the flap that supplies air to the side windows. As a result, if you put the damper on the legs, then approximately 50% will go to the side windows, 25% to the legs, and another 25% to the windshield. If you install it on the windshield, it will blow only on it.

Another reason why the VAZ-21103 stove does not heat well is that the airflow is insufficient. Let's finalize it. For this you will need anthers, as well as a grille. Using an elastic band, we attach the grille to the boot, for which we use any suitable glue. WITH reverse side We secure the boot with a clamp or tie and enjoy the result. This solution is not suitable for the driver’s seat, as it will heat up the right leg, but it’s perfect for passengers. Well, now let's move on, because we still have a lot to consider.

Possible causes of malfunction

Let's take a closer look at why the VAZ-2110 stove does not heat well. The reasons for this can be very diverse. One of the most common is that there is no coolant, or its quantity has fallen below the minimum mark. To find out if this is so, you need to look into and check the level, if necessary, add antifreeze or antifreeze. Another quite relevant reason may lie in the heater core itself. It fails quite often and remains cold when it should be hot. It is not uncommon for a gap to form in the radiator on the “ten”. It is quite natural that if there is a crack or hole in the case, it will not heat.

An air lock is another cause of radiator failure. In the best case, it can be eliminated if you drive your front wheels onto a small hill with the engine running at medium speed and stand there for several minutes. Sometimes it is enough to simply replace the filter in the cabin. As you can see, it is not so easy to understand why the VAZ-2110 stove does not heat well. There may be other reasons, for example, in the ACS controller or micro-geared motor. If in some cases you only need to spend five minutes to fix the problem, in others it may take much longer. Let's see what to do if the heater completely refuses to work normally.

Temperature sensor faulty

Quite often the following problem occurs: you cannot correctly adjust the temperature in the cabin because the sensor located near the light bulb has failed or is not calibrated. Most often, the problem is a failure of the control unit, as well as incorrect position of the damper. Fortunately, all this can be solved quite simply; you only need a little time and a tool. The first step is to diagnose the serviceability of the temperature sensor. This can be done as follows: move the heating control knob to one side, and then to the opposite. In this case, the temperature of the air entering the cabin should change.

If the temperature changes, but the VAZ-21102 stove still does not heat well, then the problem is not with the controller. If there are no changes, it makes sense to replace the sensor or simply try to turn it off and check the functionality of the heater. If the controller is turned off, air will flow into the cabin at the temperature that was set to electronic unit. If we talk in simple words, then you can disable mode “A” on the fan. Well, now let's go further and look at a few more malfunctions of the stove on the “ten”.

The VAZ-2110 stove does not heat well at idle

If you notice that one “fine” morning with the engine warmed up and turned on, you need to take action immediately. Most likely, the problem is a faulty thermostat or pump. In principle, the design of the stove is quite simple, and the point is to hot antifreeze got into the heater radiator. A fan blows cold air through the radiator, which during this time heats up and passes into the cabin. If a flow that is not hot or even warm enters the cabin, then you need to look for a problem somewhere. One of the main reasons may be a broken cylinder head gasket. In this case, the system will be in an airy state. Immediately pay attention to the large cooling circle and the functionality of the thermostat.

But this is not the worst that can happen. The situation is much sadder when the VAZ-2110 stove (8 valves) does not heat well due to a faulty pump. In this case, the engine may overheat, since antifreeze does not circulate through the cooling system. If the stove is working several times worse than before, check the pump. A faulty faucet is another pressing reason. In this case, the inlet hose will be hot and the outlet hose will be cold. If you can’t open the tap manually, just replace it; sometimes regular cleaning is enough

If the gear motor or heater is broken

In most cases, this element cannot be repaired; it is much easier to replace it. This is very simple to do, and now we will look at the sequence. If the VAZ-2110 stove does not heat well, the thermostat and pump have nothing to do with it, and there is no air lock, the air still blows cold or barely warm, then you will have to change the gearmotor. To do this, remove the windshield wipers and dismantle the frill (you need to unscrew three screws). Next, disconnect all the wires that go to the gearmotor and remove it. Then just connect new part and with the help of a friend, you adjust the air entering the cabin.

Sometimes it makes sense to check the heater directly. It breaks quite rarely, but no one is immune from this. To verify whether it is malfunctioning or working properly, you must remove the main deflector. Then you need to straighten the fasteners. It is more convenient to move the flap from the side of the engine compartment. A large amount of scale, just like mechanical damage(crack, hole, etc.) indicates that replacement will be needed. Remember that if the VAZ-2110 stove (injector, 8 valves) does not heat well and the problem is in the radiator, then you will need to completely disassemble the stove in order to replace it. This is not so easy to do, but with due diligence and free time you can do it yourself.

The stove does not heat the air well or the airflow is not of sufficient quality

Sometimes the air heats up very slowly, which is clearly not a delight, especially in severe frosts. In addition, it also happens that the quality of the warm flow is not very satisfactory. In this case, it is necessary to replace the plastic damper with an aluminum one. The latter costs a little more, but its efficiency is many times higher. As practice shows, many drivers are faced with the fact that the old-style damper bends during operation, which leads to loss of heated air. If you are willing to pay for heat in the cabin, then purchase a heater from a VAZ-2112. It is slightly better, although it may not have a cleaning filter or will not have a recirculation function (depending on the model).

You can also purchase it. It is needed to preheat the engine and interior of the car. If you are not satisfied with how well the air is supplied to the side windows and under your feet, then you can easily improve the system yourself. We have already told you how to do this. Please note that the nozzles may be either blocked by something or clogged. So, drivers often cover them with mats without knowing it. But all this is quite easy to fix, you just need to devote a little time. As you can see, if the VAZ-2110 stove (injector) does not heat well, then there can be a whole host of reasons. Most often, everything can be fixed on your own.

About problems with the damper

As noted a little above, two types of dampers are installed at the manufacturer: old and new. In the first case, it is plastic with a foam rubber seal. It does not shine with special quality and quickly breaks down during operation. The second type is more reliable, since the damper is metal and the seal is rubber. So, on the VAZ-2110 there are two dampers: upper and lower. The first is responsible for supplying cold air to the cabin, the second is responsible for supplying warm air. If, when switching with the handle, you hear the damper moving, but the air is cold, both blowing and blowing, then it is quite possible that the drive or the damper itself has failed. In the latter case, it is easiest to change it to a new one. In some cases, it makes sense to use glue, such as dichloroethane. However, you need to understand that for this you will have to disassemble the heater, and this is a labor-intensive task.

Using the SAUO controller, move the lever to minimum. Cold air should be blowing. If you turn it to maximum and there is no flow, this indicates a malfunction of the lower damper, which is responsible for supplying warm air. But at the same time you need to monitor whether the top one closes. If there is no cold flow, then it is closed. Another probable reason is jamming. This happens due to a banal misalignment or jamming due to rust. You can try to remove the central deflector, reach to the damper with your hand and try to move it there. This element may not fully open or close. In this case, the easiest way is to replace the damper with a new, better one.

Conclusion

As you can see, if the VAZ-2110 stove (carburetor or injector) does not heat well, then you first need to understand what the cause of the malfunction is. Solving this problem can take just a few minutes (for example, shutting down) or a whole day (removing the lining and repairing the mini-gearbox or replacing it). We can say with great confidence that some kind of malfunction will appear sooner or later. The point here is rather , not due to the driver’s negligence, but to the quality of the assembly. Nevertheless, Volzhsky. automobile plant produces a very passable automotive equipment. Well, that’s basically all that can be said about what problems there are with the stove and how to deal with such malfunctions. Each case of heater failure is individual, so you may not find a solution in this article. However, here are the problems that are encountered most often. You can save several hundred or even thousands of rubles on repairs and do everything yourself. In return, you will receive valuable experience that you can easily use in the future to modify or repair your car’s heater.
