Electric windows (EP) are one of the vehicle elements that contribute to more comfortable driving. Like any other electrical circuit component, EDs tend to break down periodically. What to do if a car window regulator does not work and for what reasons these components break - read below.
Components of the window lift system
What should I do if the right one does not work or both electronic devices fail? The window regulators may break, leaving them unable to lower or raise the windows. It is possible that the electronic device is jamming or sticking, but before you repair and disassemble the system yourself, you need to understand its structure. The unit itself works by controlling electric motors installed in the vehicle doors and designed to raise and lower the windows.
The system itself includes the following components:
- electric motors;
- switches located in the doors;
- wiring;
- glass
General structure of the ED system
Prevention and care of the VAZ-2109 stove
To avoid problems with the stove in cold weather, it is recommended to periodically maintain the system. Use the following recommendations:
Clean the radiator from internal contaminants that may accumulate during long-term use. Use only high quality coolant. You should not save on such consumables. Low quality products can clog the system or damage the rubber pipes. Accordingly, it is better to use a good antifreeze than to subsequently incur additional expenses on repairing the cooling or heating system. Check the thermostat's operation regularly. This device is designed to maintain a certain temperature in the system
If the unit jams, the liquid will not flow into the stove radiator, and the motor will begin to overheat. Pay attention to the condition of the fan bearing. From time to time it is recommended to lubricate this element.
To summarize, we note that in the absence of preventive maintenance during the operation of the car, in any case, problems with the heating system on the VAZ-2109 will someday “come out”. In the article we looked at how the stove on the “nine” works, as well as the main malfunctions and ways to solve them. If you were unable to identify the reason for the incorrect operation of the VAZ-2109 heating system, then we recommend contacting a service center. This approach will save you time and money.
Principle of operation
Why do the power windows not work or only the right window does not go up? To understand exactly why the malfunction occurred, it is advisable to familiarize yourself with the operating principle of the unit. Typically, such a system has a trapezoidal design, which allows the windows to be raised and lowered by pressing switches. The buttons themselves can be located in all car door cards or located only in the driver’s door. It is also worth noting that an electric motor is mounted in each door, which operates in two directions.
In addition, each system is equipped with a special relay, the purpose of which is to control the voltage supplied to the electric motors of the structure. Depending on the vehicle, some car models may be equipped with automatic switches that are installed separately for each electric motor. The use of such structural elements makes it possible to ensure normal operation of the entire system if the window regulator is poor on only one door.
Main stove malfunctions
As we have already mentioned, the stove is connected to the internal combustion engine cooling system. Accordingly, heating problems may arise for the following reasons:
- Insufficient amount of coolant in the system.
- Clogging of radiator tubes.
- There are air pockets in the system. To eliminate them, you will need to unscrew the cap of the radiator or expansion tank and let the engine idle for a while.
There are a number of cooling system malfunctions that can also affect the performance of the VAZ-2109 heating system. We look at the most common ones.
The weak point of the heating system is the valve through which antifreeze enters the heater radiator. This unit may leak. In this case, it must be replaced with a new one.
Poor quality coolant causes damage to rubber pipes due to its aggressive chemical composition.
Check the condition of the pump, which is responsible for pumping antifreeze and circulating it in the cooling system.
Poor operation of the stove can be caused by incorrect operation of the electric motor that drives the heating system fan.
If you notice extraneous sounds in the operation of this motor, this is a signal for a number of problems:
- Possible overheating due to fuse failure.
- When operating at low speeds, warm air does not flow - the electric motor has failed or there has been a break in the electrical circuit of the heating system.
Check the condition of the heater core regularly. It can become clogged during operation, and this provokes an insufficient supply of antifreeze. To carry out preventive work, you need to dismantle this element and wash it. If the part cannot be cleaned, then it is better to buy a new one and replace it.
Experienced car enthusiasts claim that the problem of poor operation of the stove may be a loose fit of the damper. Because of this, cold air from the street enters the cabin, and warm air goes to the feet. To solve this problem, just adjust the damper using a special control lever. It is located next to the gas pedal. Use pliers to tighten the cable that goes to the damper. Make two turns around the head of the bolt that secures the cable to the control arm.
If these steps do not help solve the problem, then inspect the joints of the pieces of foam rubber or plastic. Perhaps cracks and gaps have formed there. You can solve the problem with the help of sealant or simply change the insulation.
Instructions for replacing the electric motor
Repairing a window regulator may include different stages depending on the breakdown. In this case, we will tell you how to repair a window regulator by replacing its electric motor; as mentioned above, this problem is one of the most common.
The replacement process is considered using the example of a Lada Kalina car:
- First you need to buy a new electric motor, which is sold in a housing with a gearbox. The door trim is dismantled - this operation cannot be performed in the cold, since the trim is fixed using plastic pistons, which will quickly break.
- Unscrew all screws and other fasteners securing the inner handle.
- All wires must be disconnected; for greater convenience, you can remove the speakers. After these steps, the glass, which is fixed in the guides, is unscrewed. In order for the glass to sink to the bottom, you need to unscrew four more screws; to do this, use a 10 key. There is a curtain at the bottom of the glass unit, which must be removed.
- The window regulator itself is mounted on nuts and guides, the electric motor itself is secured with three more nuts. The block can be pulled out through the technological holes in the door. If you disassemble the gearbox, the electric motor will fall apart into two parts. In general, the gearbox must be dismantled and replaced with a new one, further reassembling in the reverse order. The gear cable should be lubricated before use.
Finalization of ESP VAZ 2110
- Modify the ESP (power window) fastening, then the glass will go lower, but not all the way.
- Make a small cut in the door for the glass, then the glass will be completely hidden in the door
And now in detail:
Modification of the VAZ 2110 electric window
This method will allow you to lower the glass 40mm lower, that is, only 10mm of glass will remain sticking out of the door. It will not be possible to lower the glass even lower into the door, because the standard ESP mechanism and the design feature of the door and glass do not allow this (the glass rests against the edge of the door). The point of this method is to remake the holes for fastening the ESP in the door, as well as attaching the glass itself to the ESP mechanism. Required:
- Drill (drills for 5, 6 and
- File (small circular)
Procedure: Re-drill the holes for fastening the glass to the ESP to the very bottom. Lower the lower fastening (stop) of the glass, which prevents the glass from falling lower. We lower this elastic band lower by 1-2 cm. We drill out the welding of the stop, we take everything out

Yesterday the following happened: I closed the driver's window and opened the passenger window. About five minutes later I tried to open the driver's side - no sound. I closed the passenger side. After a while I tried to open it - and it stopped showing signs of life.
It is noteworthy: when you press the buttons to close the windows, a characteristic blinking of the headlights is noticeable - a subsidence (there is a load - this was the case with working power windows). When you click open, no changes are visible.
How the stove works on a VAZ 2113
Wanting to understand the question of why the stove on the 2113 VAZ model does not heat well, you need to study the design of the interior heating system itself.
Structurally, several main elements can be distinguished. The stove consists of:
- housings;
- radiator;
- radiator pipes;
- ceiling tap;
- air ducts;
- dampers;
- fan;
- control unit.
It is malfunctions on the part of these elements that may be the reason why the stove does not heat well.
Heating of the air entering the cabin is carried out due to the fact that hot air flows pass through a heat exchanger (radiator), inside of which coolant (antifreeze or antifreeze) heated from a running engine circulates.
On VAZ 2113 heaters, it was possible to shut off the supply of cooling liquid to the stove radiator. This allows you to turn off the interior heater when it is not needed. This mainly applies to car operation in the summer.
The supply of antifreeze is shut off with a special tap, which is cut into the coolant supply pipe to the stove radiator.
The radiator itself is located inside the heater housing. In addition to the fact that the housing contains the main elements of the stove, it also does not allow heat to dissipate in different directions and controls its movement throughout the car.
The housing is securely connected to the air ducts. It is through the air ducts that hot air flows can flow to the side windows, onto the windshield, into the passenger compartment, as well as to the feet of the driver and front passenger. To control the flow of air, deflectors are used at the ends of the air ducts.
To distribute air flows to different zones, dampers are used inside the stove body. Structurally, the stove on the VAZ 2113 has 3 types of dampers:
- Control. The first damper is responsible for controlling the stove itself. It is used to redirect the air flow through the heat exchanger (stove radiator), or bypass. In the first case, hot air will flow into the cabin, and in the second, the ventilation of the car interior is simply activated.
- Supply to the windshield area. The second flap helps redirect air towards the windshield. This is a useful feature. Especially in winter. Helps remove ice from glass, as well as get rid of fogging caused by the temperature difference between inside and outside.
- Redirection to the feet, side windows and interior. The third damper, which allows you to choose exactly where the hot air will blow.
Using the stove valve and dampers, the driver controls the interior heater, directs air flows and determines the zones where they will be directed.
There is also an important element in the form of a stove fan, which is part of the heater. With its help, air flows are created. The power supply circuit of the fan motor is equipped with rheostats. This allows you to select one of 3 operating modes. That is, by choosing one mode or another, the fan rotation speed changes
It is important to take into account that rheostats affect precisely the reduction in the speed of rotation of the blades. This is useful to know when identifying stove malfunctions.
The system used on the Samara and Samara-2 families, which includes the VAZ 2113 model, differs from the classic VAZ. Previously, the fan sucked in air. Now the process of pumping air into the stove body takes place. This significantly increased the efficiency of air supply.
Plus, access to the fan has been simplified. Now you can reach it through the engine compartment, near the engine shield.

“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.
Connection diagram for power windows on doors on cars of the VAZ 2110 family: 1 - mounting block; 2 — ignition switch; 3 — right front door power window switch; 4 — right rear door power window switch; 5 — gear motor for the electric window of the right front door; 6 — gear motor for the electric window of the right rear door; 7 — gear motor for the electric window of the left rear door; 8 — gear motor for the electric window lifter of the left front door; 9 — left rear door power window switch; 10 — left front door power window switch; 11 — relay for turning on electric windows; A - to power supplies; B - to the instrument lighting switch; C - the order of conditional numbering of plugs in the power window blocks
If the window regulator malfunctions, for example, when you press a button, the window opens, but does not lock and immediately closes itself. Or the button stops working until you turn the ignition off/on. The cause of the problem is the button. It should be removed, the contacts cleaned, and replaced if necessary.
How does the stove work in a car?
Before you begin to identify the reason why, when the car is stopped, the stove refuses to heat, we recommend that you understand how heating works. After all, knowing the basics of its functioning, you can easily find a breakdown.
Both the small sedan and the truck are made of metal. Therefore, the body is strongly affected by temperature changes:
- In hot weather, the car warms up to a temperature of 40–50 degrees Celsius. In winter, it will be only a couple of degrees warmer in the car than outside. To move your car comfortably during the summer months, we use an air conditioning system.
- During the cold season, you can maintain optimal temperatures in your car using a heating system. Moreover, in our country you have to use the stove most of the year, so it must provide heat.
Previously, the car was warmed up using a stove-stove, as well as gas lamps. And only in 1917, they began to install an autonomous heating system on cars produced in America: the car began to heat up due to the heat from the exhaust pipe. For example, this heating method was used in the 1929 Ford Model A. In addition, cars began to warm up with an installed radiator, which was blown by a fan. This heating system was used on General Motors models. Over the years, every car began to be heated using such a system.
Each modern car is equipped with a heating unit, which is made of such components as:
- fan motor;
- air duct system;
- inlet and outlet pipes;
- stove heat exchanger;
- faucet that regulates the supply of coolant;
- heating equipment control unit;
- dampers, the drive of which can be mechanical or electric.
Usually the car is equipped with a stove, which is located behind the front panel. 2 tubes extend from it, supplying coolant to the radiator. It moves thanks to a pump (pump) both through the engine cooling system and through the heating system.
Heat exchange is possible due to the heating of the motor. Its cooling occurs due to antifreeze: it takes away thermal energy. The heated antifreeze enters the radiator of the stove, which heats according to the same principle as a standard battery in your home. At the same time, the stove fan starts working. It ensures the movement of cold air through the radiator. Here again there is an exchange of heat: the air is heated by the radiator, cooling it at the same time.
The heated air flow is directed into the cabin, and the cooled antifreeze enters the engine, where the heating process begins again. This heating system is used in most cars because its efficiency is quite high. In winter, the car will warm up provided that air with a temperature of 30 degrees Celsius is blown from the stove. This not only ensures that the interior is warmed up, but the windows also remain fog-free. A blower mode switch is installed on the dashboard. With its help, you can change the location of the dampers that regulate the air flow. It can be directed straight, down, up.
Almost all the time, warm air should be directed upward - that is, onto the windshield. This is the only way to maintain an optimal level of pressure in the cabin, when condensation does not form on the glass, and dust microparticles do not penetrate inside the car.
The stove plays the role of another radiator. Therefore, when the car is cold and you turn on the heat, the entire system begins to cool down. As a result, the walls of the radiator rust, the engine, like the car, takes longer to warm up. Air humidity rises, windows fog up from the inside. This means that the stove can only be turned on if the coolant temperature has risen to at least 50 degrees Celsius.
Video “How to properly install the SP control buttons?”
Separately, it should be said about installing the control buttons - detailed instructions are given in the video below (the video was published by the MoroLya channel).
Car : VAZ-2110. Asks : VasyoK The essence of the question : the power windows on the VAZ-2110 do not work, where can I look for the relay?
My window does not respond to the button, it does not go down at all. It’s not frozen, but it doesn’t budge. The passenger one seems to be the same, it’s unclear, it’s frozen. Where should I look for the driver's door power window fuse, or is it just a relay?
Mechanical problem
If voltage is supplied to the window lift motor, but the window does not move, it means that something is interfering with it, or the power window motor is faulty.
Why doesn't the window lift motor work? One of the reasons is retraction or sticking of the drive motor brushes. To check this, turn on the ignition and press the power window button while simultaneously knocking on the car door several times. The brushes will come off and the ESP will start working. How to repair the window regulator in this case? You should remove the motor casing and pull out the rotor. Clean off deposits where the brushes touch with fine sandpaper.
The power window does not work, you can hear a growling sound, but the glass does not stand still, or the window regulator is stuck. Perhaps the plastic gear in the gearbox has worn out, as a result it sticks tightly in the extreme closed position, or slips and therefore cracks. Is there a loud noise when the window goes up/down? Most likely the bearing in the window regulator motor is to blame.
The power windows have stopped working, but there is noise when you press the button, and replacing the motor did not help? The power window cable may have frayed due to overtightening. The window has opened, but the window regulator does not raise it back, but can it be raised and lowered by hand? The window lift cable broke or simply flew off the guides.
Another malfunction of the window regulator, when the glass seems to jerk, trying to close. Most likely the problem is that the glass is skewed, or something got on the rail or roller.
The power windows don't work well. Try to lubricate the window lift mechanism, as well as the glass guides. If this helps only temporarily, then try adjusting the glass and the window regulator itself.
If the window regulators operate slowly, try lubricating the window regulator mechanism and the window guides. Perhaps this is the maximum speed of their operation, so the only correct solution would be to replace them with new ones (see which ESP to choose).
Have you ever had to repair window regulators?
Basic malfunctions and methods for their elimination
There can be many reasons for the malfunction, here are the most common ones.
Warm air does not flow well into the cabin or does not flow at all
Malfunction of the fan or switch handle - one of the common reasons is a breakdown of the electric motor of the fan, wiring, or switch handle.
Test methods - to check this fault it is necessary; turn on the vehicle ignition, turn the control lever to the first position, listen.
The sound of the fan should be audible in the cabin, if not, then you need to open the hood and listen there. If the sound of the fan is not heard, the reason is in it or the switch.
Troubleshooting - remove the fan motor, check it, if it is fixed, check the serviceability of the wiring and the switch handle and fix the problem.
Malfunction of the air ducts - if the fan is working, but the air does not enter the cabin.
Test methods - to check, you just need to turn on the heater fan, open the air ducts and check with your hand one by one whether air is supplied to the windshield, side windows to the feet and the top of the driver and passenger.
Elimination - you need to check the air ducts; most likely they are clogged with dust, leaves or fluff. If again air does not enter the cabin, you need to check the functionality of the air duct dampers.
Cold air is blowing from the stove VAZ 2109, 21099
On a frosty winter day, going on a long trip, planning that this trip will be comfortable thanks to the stove, turn it on and... be horrified, because cold air is coming from the stove! What to do in such a situation?
The simplest way to solve the problem is to tighten the radiator damper cable. It can be found on the radiator housing, located near the gas pedal.
Front-wheel drive VAZ models often experience a breakdown such as incomplete opening of the heating tap. Diagnostics is carried out by comparing the temperature of the radiator pipes. In the case when the temperatures differ, we can say with confidence that the tap is not closed completely, which is why cold air is blown out instead of warm. The solution to the problem lies, again, in tightening the valve control cable and adjusting it.
It also happens that the air pumped by the stove escapes through the cracks in the air vents. Leaks lead to this problem. A simple sealing of the seams will help return everything to normal and again enjoy the warmth of your favorite stove.
Antifreeze leak VAZ 2109
Antifreeze leakage in the ninth VAZ model is one of the most common problems. This suggests that, first of all, you need to work on the cooling system; it’s time to change the pipes.
But why does the release occur?
Firstly, this may well be trivial wear and tear of components. As a rule, hoses and pipes fail to work properly, since they are made of fragile material in VAZ cars.
Low quality parts, as well as defects and wear, directly affect the health of the radiator. Components from a careless assembler lead to multiple problems that have the most detrimental effect on both the heating system and the entire operation of the car.
One of the most vulnerable elements of the stove is the expansion tank. Plastic, this word alone makes one suspicious, is not able to withstand such powerful loads that fall on this part, which is certainly important for the car. And, if many foreign cars are equipped with a reliable, durable tank, the domestic manufacturer has not yet thought of this trick and year after year produces cars with a plastic tank that regularly becomes incapacitated. It is useless to repair it; it is easier to replace it with a new one.
Now it’s worth figuring out how to determine the release of coolant.
If oil stains remain under the car when parked for a long time, there is no doubt that antifreeze is leaking.
This problem can also be determined by the smell: during normal operation of the car, the interior should never smell of it.
Sometimes you can see white smoke coming out of the exhaust pipe. Poor quality gasoline? It’s possible, but more likely it’s an antifreeze leak.
You can prevent breakdowns by regularly checking the condition of the car and its components for wear, especially the timing belt.
Now that all the basic m are known
points regarding the malfunction of the VAZ 21009 radiator, you can safely try your hand as a car mechanic. A little skill, patience and a detailed description of the diagnostic procedure will help you avoid mistakes and unnecessary expenses at the service station.
Good luck on your journey!
