With the arrival of winter, all vehicle functions related to heating become especially important. It is difficult to imagine a driver who would enjoy the touch of his back to a cold seat. In such a situation, the surface will take a long time to gain temperature, not to mention the enormous harm to health.
Everything is easier with heated seats. It takes no more than a minute to warm up the surface, after which the pleasant warmth penetrates through clothing and reaches the human body. With this option, winter driving causes fewer problems, including for the health of internal organs. But what to do if seat heating is provided, but for some reason does not work? In such a situation, the only correct solution is to repair the faulty unit.
How to repair a heated seat: all methods
Knowing the reasons for the malfunction is already half the success. To avoid wasting time, figure out why the heated driver's seat is not working. There are several main reasons:
- Burnout of the fuse insert.
- Broken circuit inside the heating tape.
- Damage to the switch or control panel. The first one is usually mounted under the car seat.
The problem with heated seats in many cars is their low level of reliability. For the most part, this applies to budget cars, whose manufacturers save on additional options. It is enough to rest your knee on the chair for the seat heating circuit to be damaged. The result is that the device does not work.
As for expensive cars, such problems occur less frequently. The reason is the use of high-quality and mechanically resistant heating tapes. But even in these cases, malfunctions are possible.
Checking fuses
The efficiency of seat heating depends on the correct operation of the on-board network. That is why, before carrying out the main activities, it is worth starting with the fuse. Please note that the failure of the latter can be determined by another sign - the absence of light on the switch bulbs. Otherwise, we can draw a conclusion about the serviceability of the part.
So, if the heated seats do not work, remove fuse F33 (rated at -15 Amperes). The fusible insert is located in a block located at the bottom of the dashboard (on the right side). If the bulbs do not light up, replace the fuse.
Where is the best place to start repairing?
A breakdown of the driver's seat heating system is a serious problem, so be prepared for the need to dismantle and disassemble the seat. In the simplest cases, you can do without this, for example, in case of cable damage.
If suspicion falls on the switch, then it will have to be removed. Theoretically, this is possible without dismantling the seat, but, in practice, it is better to remove the seat from the cabin. The recommendation is due to the fact that approaches to the switch are difficult. That is why, when removing a part from a fixed chair, you can damage not only the casing, but also the switch itself.
In a situation where the switching device is not working and needs to be replaced, start by removing the connector. To do this, rock the part from side to side while pulling it down. If it does not give way, do not use excessive force. Some manufacturers provide a special type of fastening that provides an individual approach to separation. Do the following - take a screwdriver, get inside the casing and create a little pressure. Now pull the part until it disengages.
There will be three contacts before your eyes. Between left and right, measure the resistance (the contact in the center is responsible for the light bulb). Please note that the switch contains the following elements - a contact group, a board and a slider. The latter's task is to close the contacts using a resistor.
If, when changing the position of the adjusting wheel, the resistance does not change, check the contacts. It happens that heated seats do not work due to grease getting on them. To solve the problem, just clean the contact group (everything should work).
Checking the heating tape for serviceability
If the described recommendations are followed, but the heated driver's seat still does not work, check the heating element for serviceability. The advantage is that you don’t need to dismantle the chair to do the work - just a little knowledge and skill is enough. The algorithm of actions is as follows:
Why do you need heated seats?
Having such an option in the car is extremely necessary during periods of severe frost. Getting into a car that has been parked in the cold for a long time is unpleasant and dangerous for the health of the driver and passengers.
Overheating of seats also poses a danger to human health, as well as to the car.
There are many articles on the Internet about the benefits and harms of heating. Let's dot all the i's. Driving with a heater for long periods of time can be harmful to women and men. Accordingly, it is recommended to use the option consciously in order to protect yourself from cystitis or prostatitis.
General rules for using heating:
- Do not allow the seats to become overheated significantly.
- In cold weather, turn on the heating and do not sit on them for a while.
- Once the seats have been warmed up, turn off the system. Next, heat the interior with a stove.
- You cannot stay in the cabin in warm clothes for a long time.
Following these rules will allow you to protect yourself from overheating and not harm yourself.

To do this, you need to select a suitable heater plate (there are good sets for heating seats from the EMELYA brand with intelligence) and install it in your car seats.
In the heating diagram for the VAZ 2110-12 it is indicated: 1 – mounting block; 2 – ignition switch; 3 – relay for turning on the heating of the front seats; 4 – heating element of the right front seat; 5 – heating element of the left front seat; 6 – switch for heated seats in the car; A – to power supplies; B – to the instrument lighting switch.
Operating principle of heated seats
At the head of the system is a heating element, which is connected to the on-board network of the machine. The parts are placed in an elastic panel and mounted in the front seats. The systems are divided into two types: some are built into chairs, others are made in the form of seat covers. The operating principle of both types is almost the same.
The heating elements are treated with a special coating that insulates them from direct contact with the upholstery. There are designs with one or two heating elements. The heaters are connected to the vehicle's electrical network through a control unit. Some system models allow you to adjust the temperature.
A sensor that controls heating is placed next to the heater. When the required temperature is reached, the system turns off the power. It is also possible to have a function for automatically maintaining the heating level, which is set by the driver. Other systems are controlled by a timer.
Dual-element built-in units can provide a quick warm-up, after which the system switches to lower power and less heat. The number of modes depends on the heater model.
Stories from our readers
“Fucking basin. "
Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.
Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.
Heated seats on the VAZ 2110 can be installed from the factory, and if there is no such option, then you can install heated seats yourself .
Seat heating may vary: By type of heating element:
- Threads (frequent breakdown - breakage of the heating thread)
- Carbon fiber (considered more durable)
By heating areas:
- Heated seat only
- Heated seat and lumbar area (back)
By operating modes:
- On off
- Several heating power modes
- It only starts to heat up when you sit down
- Automatic temperature maintenance (standard heating has it)
- etc.
By location:
- On top of the seat cover (elementary installation)
- Under the seat cover (you will need to partially remove the covers)
25x30cm. Threads are used for heating. The heaters have built-in thermostats for electric seat heating. The thermostat circuit closes at a seat surface temperature of 25 +-5C, and opens when heated to 31 +-4C. The temperature difference between opening and closing the contacts of the built-in thermostat must be at least 5C.
The standard seat heating buttons are self-locking (we can say that the relay is built into the button). In theory, it looks something like this: relays are installed in the control unit (seat heating buttons). When you press the button, power is supplied to the winding of the built-in relay, and at the same time to the contacts of this relay. And from the contacts to the heating elements and at the same time again to the winding of the same relay, as a result the relay becomes self-blocking. When the ignition is turned off, the winding circuit is de-energized and the relay opens. When the ignition is turned on again, the relay remains de-energized and the heating is turned off. To turn it on again, you must press the button again. In fact, this is implemented a little more complicated, but I think the meaning is clear.
The standard heating warms the seat and lower back.

Connecting heated seats in a VAZ 2110
If you decide to connect seat heating via buttons , then you can use the standard diagram for connecting electric seat heating in a VAZ 2110 : First of all, you need to cut a hole for the seat heating buttons. We fasten the mass to one of the 2 nuts (in this case the wire is blue). The backlight (in this case, the red wire) can be connected to a free small plug (it goes out together with the bundle of wires to the power windows), or the backlight can be connected from the power window buttons (usually a white wire). We insert the buttons, take out the seat heating wires and lay the positive wire (in this case, gray) to the fuse block. We are looking for fuse F15 (this is electric seat heating). Turn the fuse block upside down and connect the positive wire. Standard buttons for electric seat heating can be different (with or without indication). Buttons for electric seat heating can be placed not only on the tunnel. For convenience, you can move the buttons to the doors or to the panel. Buy heated seats for VAZ 2110

Possible malfunctions with heated seats
The heating device must have a fuse. On the VAZ-2114, two such elements are responsible for the stable operation of the heating. One fuse is located in the mounting block (F16), the other is located under the dashboard.
If you notice that the control lamps do not light up when the heating is turned on, the problem most likely lies in the fuses.
Relay problems:
- The system is turned on in an electromagnetic relay, which is located under the dashboard.
- After the unit is triggered, check the voltage at terminal 87 with a multimeter.
- If operation does not occur, then you need to examine the relay winding at terminals 86 and 87 with an ohmmeter.
- If the problem lies in the relay, it needs to be replaced.
Another problem may be the usual lack of nutrition. To check this, do the following:
- It is necessary to check the power with the power off at the connectors under the seats.
- The black wire is the ground of the car, the second is the power supply, which should have 12 volts.
- Use an ohmmeter to check the resistance of the heater windings. As practice shows, the problem most often lies here. The windings burn or break.
