Along with such obvious requirements for a windshield, such as high quality optical clarity and accuracy of fit, it is necessary to meet other important requirements.

This includes, for example, a sufficient degree of torsional strength and rigidity, since not only the flange on the body frame holds the glass, but the body is also stabilized by the connection to the glass. Defective, too weak or damaged glass can crack under strong body movements, for example on an uneven track. In addition, the glass must be able to withstand the large temperature difference between the vehicle interior and the outside temperature. When heating in winter or when the air conditioner is operating in summer, the windshield is additionally subjected to strong surface stress as a result of the temperature difference inside the glass.

The original Volkswagen Polo Sedan windshield meets all the requirements.

Please note that many non-original windshields are sold without seals.
And the original bottom seal is supplied only complete with the original windshield.

Classic body lines, a spartan look of internal equipment, a reliable power plant and, of course, branded German comfort - this is how the designers and engineers from Wolfsburg created the new Volkswagen Polo sedan. Having handed over a fresh version of the car to the hands of Kaluga craftsmen, the Germans supplemented the project with "chips" developed specifically for Russian conditions.

One of them is the rear window heating option. It is standard for. There is nothing surprising in the addition. Today, it's hard to find a car that lacks the traditional filaments that stretch along the rear window.

But it was not always so. Twenty years ago, a pleasant and very convenient function was a wonder in our country. When a VAZ "five" or "seven" with installed heater threads drove through the streets, it immediately caught the eyes of experienced motorists who knew about advanced technologies. With such a novelty, it was not a sin to brag to relatives or friends.

But sooner or later everything becomes obsolete. The heated rear window option works on most modern cars these days.

The principle of glass heating

The principle of operation of the device is simple. Its main purpose is to heat the glass surface to a positive temperature. One side of the terminal from the threads is connected to the electrical system, the other to ground. The current flows into the filaments, they heat up, spreading heat throughout the entire area. Whether it's winter or summer, the function should work effectively at the touch of a button.

A very useful thing. After all, every motorist has repeatedly faced the problem of fogged or icy glasses. Agree, this is a real nightmare!

Imagine: it is raining, the windows are all fogged up due to the difference in temperature. How to take back? It will take a long time for the side deflectors to warm up the air and dissipate condensation on the glass. You have to either wait or manually wipe the surface with a rag. The third option is to use the electric heated rear window. It will deal with excess moisture much faster, providing excellent visibility for maneuver.

There may be several reasons. These include violations of the contacts of the threads to the electrical system of the sedan, a breakdown of the heater relay or a trite blown fuse.

Interestingly, in the event of malfunctions with rear heating on the Polo sedan, the only repair option that official dealers can offer is a complete glass replacement. They are not involved in restoring threads or other elements of the system. Therefore, in order to save money, it will be more rational to take the situation under your own control. Moreover, the recovery procedure does not take too much time and even a motorist without experience can handle it.

The first hypothesis that should come to mind is a blown fuse. This is the most harmless thing that can happen on a Polo sedan with a heating system. The fuse box is located under the steering column of the vehicle. The fuse is located at number 53 on the right side, in the bottom row. Its current strength is 30A. To check the suitability of an element, we call it with a tester.

If everything is in order with it or the new fuse installed in the socket did not solve the problem, we check the relay. Disassembling the device itself, of course, is not worth it - it's easier to buy a new sample. To get to the switch:

  1. We remove the negative terminal from the battery.
  2. Dismantle the radio tape recorder with an adapter frame.
  3. Using a flat screwdriver, pry the climate control system control unit underneath, remove it from the dashboard and unfold it.
  4. There are three switches on the unit: heated front seat, alarm and heated rear window. Overcoming the resistance of the latches, we take out the switch from the socket, which is responsible for heating the rear window.
  5. We mount a new switch and assemble everything in the reverse order.

If the labors did not give any result, then we carefully inspect the connectors on the rear window along the edges. It is possible that accumulated dirt or corrosion is interfering with the flow of current to the heating elements.

The biggest nuisance that can happen is broken filaments. Each strand is connected to vertical buses and operates independently of the rest of the "fibers". To determine which one isn't working, just look at the horizontal stripes on the glass.

It is much more difficult to identify the exact location of the break. In some cases, it can be detected visually. If it is not visible, then the easiest way is to use a voltmeter.

In addition to a voltmeter, you can also use an ohmmeter or an automotive probe.

If the heated rear window does not work, you can use one of the filament recovery methods. For example, a silver-based electrically conductive varnish can be used. Before the procedure, the glass surface must be cleaned. Then we glue the tape on both sides to the damaged area, apply the varnish with a thin brush and dry it at room temperature for 24 hours. In the presence of a technical hair dryer, the drying process is noticeably accelerated. The surface becomes dry after half an hour. During the process, it is not recommended to turn on the heating function, and also to rinse the surface with various solvents.

Volkswagen Polo Is a modern car from a German manufacturer that many car owners like. Beautiful body shapes and comfortable interior attract lovers of inexpensive cars. But even reliable German models have certain nuances and problems.

You can read about everything related to electrics, protection of electronic circuits and Polo comfort and highline circuits in this article. If suddenly some equipment, for example, Volkswagen Polo fuses and relays, fails, the lists indicate the necessary fuses, relays and circuits, and in the comments you will find ways to solve common problems.

This article describes fuses and relays Volkswagen polo in the ComfortLine and HighLine trim levels. The numbering and designation of some fuses in the TrendLine configuration may differ.

When determining the health of the fuses, use a tester, this will eliminate errors, quickly ring the necessary circuits or measure the voltage in the connectors. Always carry backup fuses and relays with you. they can help you out at the time of an unexpected breakdown or short circuit.

Salon block:

Passenger compartment fuse box:

The fuse box in the passenger compartment is located in the lower part of the dashboard, under the steering wheel. To get to it, you need to open the protective cover.

Fuses No. 1-24:

1 - reserve.

2 (10 A) - steering column switches, windscreen washer... If the windshield washer does not work, check the fluid level in the washer head, in winter, check if the fluid is frozen in the system pipes and injectors. Supply power from the battery to the pump-pump, if it does not work, replace with a new one. If it works, check the wiring, connectors, terminals and the right steering column switch.

3 (5 A) - fuel pump, engine control system unit... If the fuel pump stops pumping gasoline and does not create the required pressure in the fuel system for engine operation, check, in addition, fuse 36, power fuse SA3 and relays R4, R8. If the fuel pump does not work when connected directly to the battery or works intermittently, replace it with a new one.

4 - reserve.
5 - reserve.

6 (5 A) - dashboard... If the arrows, sensors or the on-board computer display on the dashboard stop working, check, in addition, fuses 18, 20, 38. Also check the connector with wires on the back of the dashboard.

7 (5 A) - license plate lighting lamps, headlight range control.

8 (10 A) - fuel injectors.

9 (5 A) - anti-lock brakes ABS... If the ABS system stops working and the lamp of the same name comes on on the dashboard, check the power fuses 1, 4 and SA5 under the hood, as well as the sensors located at the wheels. Most likely their wires are frayed, broken off, or the connector is loose. After locksmithing with the front suspension, when assembling units, they may forget to install the sensor wires in special holders, because of this, they usually fray. If any sensor is defective, replace it with a new one.

10 (5 A) - starter relay circuit, electrical control, speed sensor... If the starter does not work, check also fuses 19, power fuse SA3 under the hood and relay R3. If you bought a car from the passenger compartment recently, and in cold weather stopped turning the starter (clicks), most likely the oil has frozen in it, you need to warm up the car.

If the car is no longer new and the starter does not turn, check the battery charge, charge it if necessary or install a new one. Check the contacts of the terminals on the battery, if they are oxidized, clean their inside and tighten them firmly. Check the operation of the starter and relay by closing the contacts on the retractor (with the gear off, in neutral).
If the speedometer stops working or is intermittent, most likely the matter is in the speed sensor and its contacts.

11 (5 A) headlight range control mechanism.

12 (5 A) - electrically adjustable side mirrors... If the mirrors stop adjusting, check the wiring between the body and the front doors, and inside the mirrors themselves. To turn on the heated mirrors, turn the mirror adjustment joystick 180 degrees.

13 (15 A) - automatic transmission control.

14 (5 A) - airbags... When starting the engine, the dashboard airbag lamp should come on for about 5 seconds and then go out. If it stays on, then there is a malfunction or a stored alarm error in memory. Diagnostics is needed to establish the exact cause.

15 (5 A) - heated washer nozzles... The nozzle heating works when the mirror heating is turned on (turning the joystick 180 degrees). If it does not work, check the connections and the condition of the wires under the hood at the point of connection to the injectors.

16 (5 A) - parking sensors.

17 (10 A) - e / m adsorber valve, lambda probes.

18 (5 A) - rear fog lamp, dashboard.

20 (5 A) - steering column switches, dashboard... See prev. 6.

21 (10 A) - light in the cabin and trunk... If the ceiling light does not work in any position, check the lamps in it, the switch and the wiring. If the light does not come on only when the doors are opened, check the limit switches in the doors, their connectors and the wiring from them to the control unit.

22 (5 A) - climate control, key lock in the ignition lock... If cold air blows when you turn on the stove and set the hot temperature, most likely you have a low level of antifreeze in the tank or air has entered the cooling system.

Also check if the air intakes, fan and radiator are not clogged, clean if necessary. It may also be in the dampers, check that they open and close correctly. If the heater motor does not spin at all, check its serviceability by directly supplying 12V power to it.

23 (7.5 A) - electrical control, engine control unit, automatic transmission mode selector.

24 (5 A) - heated side mirrors.

Fuses No. 25-60:

25 (5 A) - radiator fan, air conditioning, pressure sensor... If the fan does not work, see power fuse 2.

26 (7.5 A) - electric power steering... If the steering wheel begins to spin tightly or there are problems in the operation of the amplifier, check, in addition, the power fuse SA4. Do not leave a parked car with completely turned out wheels, and also do not keep the wheels turned out all the way for more than 5 seconds to avoid damage to the EUR. The EUR itself is located on the shaft in the steering column.

27–32 - reserve.

33 (5 A) - brake light switch... If the brake lights stop lighting, check, in addition, fuse 43, as well as the lamps, their connectors and the brake pedal switch, wiring.

34 (7.5 A) - high beam in the right headlight... If it doesn't work, check the lamp. If both headlights are off, check their lamps and the steering column light switch.

35 (10 A) - engine management system, power supply to the engine compartment electrical equipment.

36 (15 A) - fuel pump... See prev. 3.

37 (25 A) - heated front seats... If one of the front seats stops warming up, check the connector and wires under the seat. Check if voltage is coming to this connector. If there is voltage, most likely the contact inside the seat has disappeared or the heating element has broken. If there is no voltage, check the wiring and the power button.

38 (7.5 A) - high beam in the left headlight, dashboard... See prev. 34.

39 (10 A) - low beam in the right headlight... If it does not work, check, in addition, the SA3 relay, as well as the lamps and contacts in the headlight connectors. If both low beam headlights still do not work, check the light switch on the dashboard to the left of the steering wheel, its contacts, and the steering column switch, wiring.

40 (30 A) - heater / climate control / air conditioner fan... See prev. 22.

41 - reserve.

42 (15 A) - cigarette lighter... Usually only works when the ignition is on. If it stops working after connecting the device, most likely a short circuit, use an additional outlet or a splitter to connect the devices. If replacing the fuse does not help, check the connector itself, the contacts in it, the connection connector and the wiring.

43 (15 A) - direction indicators, alarms, stop lamps, electrical equipment of the on-board network. If the turn signals do not work, check the lamps and contacts in the landing connectors. If the turn signals start flashing faster or slower, check all lamp connectors for a short circuit, as well as the wiring. The case may also be in the steering column turn signal switch.

44 (15 A) - alarm siren, volume sensor.

45 (15 A) - radio, audio system.

46 (20 A) - sound signal... Usually only works when the ignition is on. In order to always work, you can reflash the control unit. If it does not work, check the integrity of the signal itself. Located on the driver's side, under the left headlight. To get to it, it is most convenient to remove the left front wheel and unscrew the wheel arch liner. Apply power to it, if it works, then the matter is in the wiring or the steering switch.

47 (20 A) - front wipers... If the wipers stop working, check the steering column switch and the gear motor. In winter, water could get into it and freeze. Also inspect the entire mechanism for blockages and ice. Check if the washer works. If the washer also does not work, try first to fix the malfunction of the washer, then the wipers. It may also be in the wiring / connectors.

48 (25 A) - central locking - locks for doors, trunk, fuel tank hatch... If the door locks do not close, check the door limit switches, one of them may have failed or the contact in the wires between the body and one of the doors has disappeared. Also check the door lock mechanisms and their drives, wiring.

49 (5 A) - reversing light... There is only one lamp on the right. If it does not work, check its serviceability and contacts in the connector. Also check the switch on the transmission (on the automatic transmission, the switch is in the selector).

50 (25 A) - electric window regulator in the driver's door... If the driver's glass rises and falls intermittently, every other time, most likely the matter is in the motor overheating. A common problem known to dealers.

51 (25 A) - electric window regulator in the front passenger door... If the windows are not working correctly, try programming them. To do this, fully open and close each glass, while continuing to hold the button in the extreme position for 1-3 seconds.

52 (30 A) - power windows in the rear doors... See prev. 50 and 51.

53 (30 A) - rear window heating elements... The electric heating of the rear window in the Polo is automatically switched off. If it does not work, check the terminals on the heating elements, the serviceability of the button and its contacts, as well as the wiring on the car body. The button can be reached by removing the radio frame.

54 (15 A) - fog lights.

55 (15 A) - ignition coils.

56 (30 A) - electric heated windshield.

57 (5 A) - front left and rear left lamps of dimensions, parking light on the left side.
58 (5 A) - front right and rear right lamps of dimensions, parking light on the right side.

If the dimensions do not work, check, in addition to these, fuse 19 and relay R7, lamps, light switch to the left of the steering wheel and wiring. The parking light is turned on when the ignition is off by shifting the steering column switch to one of the positions - either only the left dimensions will light up, or only the right ones. Function for marking parking at night.
