Why the power windows on the VAZ-2112 do not work: reasons with photos

Electric windows are relatively recently installed on domestic cars. These mechanisms are fully consistent with current trends in the industry, but are not highly reliable. Very often we hear complaints that the right window regulator of the VAZ-2110 does not work, the device on the driver’s side does not respond well to commands, or both devices turn off at the same time. How to find the cause of the breakdown and fix it without contacting a car service? We will try to find answers to this question in this article.

VAZ window lifter repair

As a rule, if the window regulator on a VAZ 2110 does not work, this does not come as a surprise. Unfortunately, these designs are not able to boast of their reliability. If the power windows on the VAZ 2110 do not work, you will have to repair them yourself. Of course, you can replace this device with a new one. Moreover, today there are many varieties of ESPDs sold on the market. But why waste extra money, especially since if the VAZ 2110’s power windows don’t work, they can be easily repaired.

Is it possible to install a homemade drive?

This question arises among many “Kulibins”.
There is no information about such devices. And is it necessary, if in our time there are no special difficulties in purchasing standard equipment? At one time, there were small boxes on sale that were attached directly to the trim instead of a handle that had to be turned by the person sitting near the door. Nowadays it is hardly possible to find such devices not only on sale, but also in warehouses of unnecessary things. And one more question that often worries our car owners: is it advisable to install such lifts from other cars on the doors of cars of early production that are not equipped with electric drives? As they say, there are no barriers for inquisitive minds and skillful hands. But we must not forget that in addition to the motors, you will have to make changes to the electrical circuit, providing it with additional relays, switches and fuses. If you have no experience working with electronics, such experiments are highly undesirable. In addition, it is not recommended to introduce design features that were not taken into account by the manufacturer. If the desire to do tuning is too strong, seek help from car service specialists who can install an electric drive on your car.

The right window lifter on Kalina does not work

VAZ (Lada) Kalina I 2004 - 2013

The power window button stopped responding to lowering, both on the driver's and passenger's sides. Right front door. That is, the glass goes up, but there is no reaction when it goes down.

I tried swapping the two top right relays in the fuse box. What else can you see?

Most likely a wiring break. Remove the door trim and disconnect the glass window chip. and check the power supply and mass for lowering. Maybe the motor itself is to blame. But most likely the break is either in the corrugation between the door and the counter. Or even lower, maybe in the threshold, there is ESP wiring. Search

You can replace the button on the right door. It’s better to first check whether the lowering voltage comes from the left button to the right, whether it passes through the right button.

The funny thing is that you end up disassembling and reassembling the engine and that’s it. It feels like when closing the window, an impact occurs and the shaft gradually disengages. I suffered with both the right and left doors.

It is easy to check the serviceability of the button without disassembling the door. With the engine turned off, you press the button and if it is working properly, the light in the instrument panel will dim slightly.

The window regulator does not work on Kalina

Where is the ground terminal for the power windows and central locking located in Kalina?

Forum → Electrical

In general, the driver's lift does not work. The motor itself is fine, there is simply no voltage coming to it. “+” comes to the button from the relay, the button itself is normal, voltage comes from the button itself of both polarities. And already on the block, which supplies directly to the motor, there is no voltage. The only thing that comes to mind is a broken circuit, but I very much doubt it, because the wires are well insulated under the noise of the floor, there was no way they could be frayed. Still, I traced these wires that go to the motor from the button. Gray-black and black come out of the button, and the same gray-black and blue-black come out of the block. The alarm also connects to the ESP (when you put it on it, they rise), so I think somewhere the black wire from the button is combined with the same blue-black wire from the alarm and it just goes to the motor. At first the motor simply did not work periodically, now it is completely silent. By the way, the alarm closes the glass. What do you advise? Still looking for a broken wire?

Here we can advise you to look at the mounting block. Test the voltage at the power window fuses. Next, arm yourself with a wiring diagram and a signaling book. In theory, the wires should run parallel, that is, the signaling should not interfere with the buttons. Follow the wire and test, test, test...

It was not there, the signaling was the one that got in the way, or rather not it, but a small box, which, as I understand it, is the power window control unit. In general, the craftsmen who installed the alarm cut the standard wire (black and blue), twisted it with another green and white one, inserted the same black one into the control button and ran the whole thing under the console. I tried, without taking anything apart, to trace these two wires. Although for the life of me I couldn’t find either black or green-white under the dashboard, I had to dismantle the floor of the cabin. In general, there were 2 more twists under the console (black turned into blue, green-white turned into green). This whole thing comes to BUS. After that, the voltage on the wire was lost (there was no voltage on the green wire, which should soon turn into black and blue), and the jumper that closes them inside itself simply glitched. As soon as I hit that box (BUS) a couple of times, the lift began to hum. Tomorrow I'll go buy a new BUS. It's called tubiron, I Googled it, they say it's rare shit. Apparently, there is a wire on the signaling device, which, when connected to it, gives out a short impulse, and the BUS, under the influence of this impulse, gives out a long signal to the power windows. Such troubles(

The power window rack is a housing in which the glass movement mechanism is located - a toothed chain drive. An electric motor is fixedly mounted on the rack, driving the mechanism.

The fixedly located gear motor eliminates the possibility of damage to the electrical wiring in the door.

The window lift rack is absolutely rigid. Thanks to this, there is no rattling, vibration or resonance when raising and lowering the glass.

Window lifters are extremely lightweight and compact. They work almost silently.

They are installed in place of the guides of the standard window regulators and secured into the standard mounting holes using the fasteners of the replacement window regulators.

Why is repair needed?

You have to resort to window regulator repair for various reasons. And most often the cause of the malfunction lies in the electric motor. This is explained by the fact that the engine housing itself is not sealed and moisture can enter it. As a result, rust appears inside, which destroys the mechanisms. If the window regulator does not work on a VAZ 2114 or another model, it is recommended to start repairs by disassembling the door. But first, let's look at the types of lifts used today:

rack and pinion windows, which are considered the most reliable of all others;
Cable SPDs, which are installed standard on VAZ models;
plank SPD.

Depending on which manufacturer produces ESPDs, they can be installed in standard locations without much modification. If they don't fit, then it's okay. The window regulator can be easily rebuilt. In addition to the fact that SPDs differ in type of design, they can also have different motors. Thus, an electric motor of domestic or imported production can be installed on window regulators. It is because of this that the difference arises between SPDs, which may have:

different speeds of lowering and raising the windows;
different noise levels during operation;
ability to work in winter conditions, etc.

What is ESP

An electric window lifter (ESW) is installed in the inner cavity of the door, fixed to its body or subframe. It consists of three main parts:

drive mechanism (gearmotor);
control systems;
lifting mechanism.

The drive mechanism creates the force necessary to move the glass. It is a small unit that combines an electric motor, gear and worm gears. Such a device provides blocking in the event of an attempt to mechanically press the glass in the opposite direction. A lifting mechanism, which can be a cable, lever or rack, is responsible for moving the glass.

Cable

This type of window lifter is essentially a flexible element: different manufacturers offer their own versions - it can be a chain, cable or toothed belt. The cable is tensioned inside the door between the rollers, and its movement is ensured by the drive drum.

Cable glass lift

When the drum rotates, the cable is set in motion - one end unwinds and the other winds up. The flexible chain is connected to the glass by a plate.

Lever

The design of this window lifter is radically different from the cable lifter, and consists of a lever, a slider and a glass fastening plate. There can be two levers; they move the glass more evenly.

Lever window lift

From the drive mechanism, rotation is transmitted to the wheel, which interacts with the lever. If the design has two levers, then there are also two wheels. Accordingly, the price of such a lift is more expensive.

Rack and pinion

This mechanism is the simplest - it is a toothed metal rack with a guide plate that connects to the glass. The movement of the plate is provided by the drive mechanism, the gear of which interacts with the rack. The glass itself moves in the door body on special rails. The rack and pinion design is quite simple and is characterized by a stable speed of glass movement. Rack and pinion window lifters are ideal for the VAZ 2109 and other domestic cars of this type.

Causes of malfunction

Minor malfunctions or breakdowns can occur for various reasons:

After an accident. If the blow hit the side door. It can manifest itself either in the incorrect operation of the window regulator or in the complete failure of this unit.
If exposed to moisture or dampness. Of course, the car door is sufficiently sealed. But in some cases, the electrical components of the power window short out due to condensation or the car being in deep water for a long time.
Installation of low-quality or defective components.

Let's look at the most common problems.

Electrical faults

Electrical faults are the simplest because they are the easiest to fix. Electrical failures can occur due to:

Poor contact on the opening control button/relay. Most often this is observed when there is insufficient contact in the switching device. Oxidized or erased power pads on the board do not conduct current in the circuit. The window regulator begins to twitch or fails altogether.
Wire shorts. The door has moving elements. The wiring in these places may fray or break. The power goes out and the glass stops going up and down.
Fuse blown. If there is a sudden jump in the car's circuit, the fuse located in the window regulator circuit may burn out.
Motor/gearbox malfunction. There can be many reasons for this: from burnout and sticking of the brushes, to oxidation of the contact group on the motor.

For any type of malfunction, it is worth carrying out diagnostics at a specialized service station. But first you should check the power window fuses. Most often, the cause of the breakdown lies in this place.

Mechanical defects of the mechanism

Mechanical defects occur much more often than electrical ones. They can also cause the window regulator to break. The most common mechanical failures:

Broken cable. A rare malfunction. With such a defect, the glass “falls” into the door frame and does not rise from the button.
Bent arms or guides. In this case, the work jams or the button is completely ignored.
Reducer gear failure. Modern cars are often equipped with plastic gears that quickly wear out, crack or crumble. The teeth begin to slip. The glass jerks or rises jerkily.
Sticking or jamming of the mechanism due to lack of lubrication. A common “sore” on old cars. The resource of mechanics is not infinite; it also requires careful treatment and timely maintenance. Over the years of operation, machine lubricant on moving parts dries out. The parts begin to rub against each other and jam together.

The listed defects can only be repaired on a disassembled door. In this case, you will need to purchase additional damaged or broken components.

Other causes of power window failure

Sometimes the glass stops opening normally for reasons that are unclear at first glance. This may happen due to:

Severe frost. Condensation forms in a warm interior. At night the car cools down, and in frosty weather the accumulated moisture forms ice where the glass meets the door. An ice crust may also form inside the lifting mechanism. All this leads to difficulties in the operation of the window regulators.
A foreign object gets into the gap between the glass and the door. In this case, the window regulator becomes stuck.

In 80% of cases, any mechanical or electrical malfunction is eliminated with a disassembled door.

“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!

In a variant version, electric windows are installed on cars of the VAZ 2110 family. The power window control keys are located on the floor tunnel lining. On a car where this option is not available, you can install electric windows yourself.

From the variety of options, we chose rack-and-pinion window lifters: their design is simple and reliable, and they are easy to install.

Sequencing

Before starting work, disconnect the negative cable terminal from the battery terminal.

From the set of wires included in the kit, we assemble a harness for connecting to the on-board network of a VAZ 2111 car (thick lines in the diagram).

Using a Phillips screwdriver, unscrew the self-tapping screw securing the latch of the mounting block.

Remove the block from the lid and turn it over.

We insert block Ш1 of the wiring harness into the corresponding socket of the mounting block.

Remove the door trim.

Through the holes in the body pillar and in the door we stretch the wires to the electric window regulator of the VAZ 2112.

When installing switches (control keys) on the lining of the floor tunnel, we pull two wires into the door. When installing switches in the door trim, three wires are required (an additional one is for key illumination). To avoid damaging the glass during work, remove it from the door.

Using a screwdriver, remove the inner glass seal from the door.

Lowering the glass slightly, use a 10mm head to unscrew the two bolts securing the glass frame to the window lift mechanism.

We take out the glass.

Using a “10” wrench, unscrew the nut of the upper fastening of the guide of the VAZ 2110 window lifter mechanism, two nuts of the middle...

...and the lower fastening nut.

Using the “8” wrench, unscrew the three nuts securing the window lifter mechanism.

We take out the window lift mechanism through the door window.

Cut off part of the protective film (it will interfere with the electric drive).

We insert the electric window regulator.

Having inserted the power window mounting studs into the holes of the door frame, attach nuts to the studs and tighten them.

We connect the wiring harness blocks in accordance with the connection diagram. By connecting the negative wire terminal to the battery terminal, we check the operation of the electric drive. We install glass in the door.

Lower the glass until the mounting holes of the glass frame align with the holes in the power window bracket.

Attach the glass frame with bolts.

We check the operation of the window regulator.

We install the power window control key in the door trim.

We install a plug in the hole in which the handle axis of the previous window lifter was located. Reinstalling the door trim

Malfunctions, spare parts, service, insurance

Here's the problem: 1. after changing the battery, all the power windows stopped working, except for the driver's. 2. The dimensions also stopped working (hence the interior lights and speedometer do not light up and the fog lights do not work). Where is the fuse for the side lights on the Prado 120 (which one)? Although, I don't know, I checked EVERYTHING, not a single one burned out. What could be the reason?

Continue topic

The power windows should be trained and they will work. I won’t say what about the side lights. (Added after 39 seconds)

Moreover, each separately!!!

If you want to train them, they don’t respond to button presses at all.

https://www.land-cruiser.ru/index.php?showtopic=43440 In order to restore these settings, after connecting the battery you need to: – press the glass control button and do not release it until the glass is completely closed with a short delay at the very least position Release the button. – press it to open the glass and hold it until the glass is completely opened with a slight delay in the extreme position. After this, the ECU will “remember” the extreme positions of the glass and the automatic opening/closing function of the glass will be restored. (Added after 1 minute)

From the owner's manual: If the battery is disconnected or the battery is dead, the power windows may not operate automatically and the anti-pinch feature may not function properly after reconnecting, replacing, or charging the battery. In any of these cases, you need to normalize the power windows. To do this: 1. Press the power window switch down and lower the window halfway. 2. Press the switch up until the glass closes and hold it for a second. Make sure the glass opens and closes automatically. If the switch does not operate properly, have it checked by your Toyota dealer.

I came across a similar problem here the other day, the ALL AUTO beet lifter, individual window lifters on each door work normally, but they don’t want to use the central (driver’s) remote control. TRAINING: Simultaneously press and hold the down button on the left rear door all the way (the glass should initially be completely closed) and the corresponding button on the central (driver's) remote control; as the glass moves down, these pressed buttons are released at the same time! THEN everything repeats only the buttons are pressed and held up. We EVERYTHING try to control the trained glass from the driver's seat; if everything is done correctly, the glass should go down and up as programmed (depending on the button). NEXT, the training scheme is “DIAGONAL”, i.e. 1) left rear 2) right rear 3) left front. For each door being trained, the sequence of actions is the same; the main thing is not to confuse the sequence according to the “diagonal” training scheme. This is exactly what happened to me, after the left rear was tuned, I tried to tune the left front and got a “cuckoo”, but after I trained the right rear and moved on to the left front, she learned without problems. GOOD LUCK in training! (Added after 18 seconds)

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).

How to repair a motor?

We have figured out the reasons why the window lifter in a VAZ 2110 car may stop working, and now we will tell you how to fix the window lifter motor with your own hands.

Before repairing the device, it must be dismantled. Do not save time and do not try to disassemble it in the door, as this is inconvenient. It’s better to immediately remove it and pull it out of the door, and then start repairing:

First, remove the gearbox cover with a 5.5 wrench - to do this you need to unscrew 4 bolts.
Remove the driven gear from the gearmotor and check the condition of the teeth on it.
Using a shaped screwdriver, unscrew the bolts that hold the engine.
Disconnect the wires from the engine and note how they were connected.
Insert the wires into the electric motor housing.
Disconnect the gearbox and motor.
Knock the armature out of the engine by holding its shaft in a vice (it is better to wrap it first so as not to damage it). Knock out the anchor through the wooden spacer with light blows of a hammer on the end.
Remove the plastic plug from the base using tweezers or pliers.
Knock out the bushing at the end of the shaft. You can make this process easier by spraying with WD-40. Next, fix the shaft and bushing so that the stop is on the bushing. Insert a thin punch and make a few gentle blows.
Remove any rust from the shaft using fine sandpaper. Additionally, it is recommended to treat the elements with gasoline or solvent.
Press the rear shaft bushing into the body of the VAZ 2110 electric motor, using a thin spacer with a hammer.
Insert the brushes into place and secure with wires.
Place the shaft into the gear housing.
Release the brushes and check for contact between them and the commutator.
Place the previously removed plastic tip on the end of the shaft and thoroughly lubricate it with some lubricant, for example, CV joint-4.
The seal on the wires must be pulled away from the terminals. Insert the wires inside the electric motor housing and then install the seal in place.
Insert the driven gear into the gearbox housing and screw the cover to the housing with four bolts.
Connect the gear housing to the electric window lift motor of the VAZ 2110. This can be done by holding the gear shaft with pliers to prevent it from turning. Otherwise, the anchor will jump out of the gearbox. Secure them with two bolts.

Do-it-yourself repair of the VAZ 2110 window lifter electric motor has come to an end, and all you have to do is check the operation of the mechanism.

Why did the window regulator stop working?

There are quite a few reasons for the breakdown of power windows on VAZ-2110 cars.
The most obvious of them are a mechanical malfunction of the mechanism itself or a broken cable. These breakdowns can be identified by visual inspection, after which they can be easily repaired with the appropriate tools. If the problem does not lie in the mechanism at all, you will have to diagnose the electrical part, which indicates the following reasons for the breakdown of the window regulator:

failure of the switch itself. To identify this problem, car services use special monitoring and measuring equipment, which makes it possible to determine even minimal deviations of the device’s operating parameters from the norm. At home, you can act by the notorious “trial and error method”. Simply install a new, known-good switch. If the problem disappears, then its cause was precisely the breakdown of this part, which now needs to be replaced;
electrical circuit break. This problem, which negatively affects the normal operation of the window regulator, can occur due to the disappearance of contact in the block. In addition, the cause of a circuit break is often contamination of the contact groups or damage to the electrical wire;
short circuit. It can be caused by incorrect operation (or failure) of the gear motor, as well as the power window switch. You can independently identify this problem as follows: replace the fuse and turn on the mechanism. If the new part burns out immediately, then the short circuit occurs exactly on the side with which we experimented. Such a simple and rather primitive diagnosis will avoid the need to disassemble both window regulators;
problems with the relay. The failure of a given part is determined by replacing it with a known good one;
fuse blown. The cause of this problem may be either the short circuit already mentioned above, or voltage drops caused by the incorrect operation of any devices. Replace the fuse with a new one - if it also burns out instantly, a complete diagnosis of the mechanism and electrical circuit is required.

Dismantling the old unit

If the electrical elements have been more or less decided, then the mechanical part of the problem is much more complicated. The described VAZ models have non-separable ESP structures. They are characterized as the most reliable, but in case of breakdown they require a complete replacement from the owner.

How the structure is dismantled.

Remove the handle and rod.
Lowering the glass, remove the holder.
The glass is raised to the maximum and secured with tape.
Unscrew all the nuts holding the mechanism to the door.
Dismantling is complete and the device can be completely removed for diagnostics.

Next, you will decide whether to repair or replace with a new device.

Why is repair needed?

rack and pinion windows, which are considered the most reliable of all others;
Cable SPDs, which are installed standard on VAZ models;
plank SPD.

different speeds of lowering and raising the windows;
different noise levels during operation;
ability to work in winter conditions, etc.

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.

Why did the window regulator stop working?

If the problem does not lie in the mechanism at all, you will have to diagnose the electrical part, which indicates the following reasons for the breakdown of the window regulator:

failure of the switch itself. To identify this problem, car services use special monitoring and measuring equipment, which makes it possible to determine even minimal deviations of the device’s operating parameters from the norm. At home, you can act by the notorious “trial and error method”. Simply install a new, known-good switch. If the problem disappears, then its cause was precisely the breakdown of this part, which now needs to be replaced;
electrical circuit break. This problem, which negatively affects the normal operation of the window regulator, can occur due to the disappearance of contact in the block. In addition, the cause of a circuit break is often contamination of the contact groups or damage to the electrical wire;
short circuit. It can be caused by incorrect operation (or failure) of the gear motor, as well as the power window switch. You can independently identify this problem as follows: replace the fuse and turn on the mechanism. If the new part burns out immediately, then the short circuit occurs exactly on the side with which we experimented. Such a simple and rather primitive diagnosis will avoid the need to disassemble both window regulators;
problems with the relay. The failure of a given part is determined by replacing it with a known good one;
fuse blown. The cause of this problem may be either the short circuit already mentioned above, or voltage drops caused by the incorrect operation of any devices. Replace the fuse with a new one - if it also burns out instantly, a complete diagnosis of the mechanism and electrical circuit is required.

Mechanical problem

After checking all sections of the electrical circuit and being convinced that everything is working, but the VAZ 2110 window lifter motor is not functioning, this may be the problem.

Turn on the ignition and press the window down button. Without letting go, knock on the door. If the window moves, change the brushes in the motor. The malfunction can be corrected after removing the motor and pulling the rotor out of it. You will notice carbon deposits that need to be cleaned off with fine sandpaper.

The next problem with the VAZ 2110 power window, related to mechanics, manifests itself as follows: if you hear a buzzing sound after pressing the window open button, but the glass remains in place or lowers jerkily, the problem is the gear of the gearbox is worn out. It must be replaced by selecting a similar part.

Another mechanical malfunction of the window regulator is this: the mechanism works, but makes extraneous noise. We will tell you what to do in this case below.

If the VAZ 2110 window regulator does not work, but you hear the sound of the motor running, check the cable - it could have burst or frayed.

Sometimes the window in a domestic car goes down, but does not go up, but you can close it with your hands. In this case, the problem is again in the cable, which could have slipped off the guide.

If the glass jumps or moves jerkily when closing, it may be warped or there may be some debris caught in the rails. You can also try simply lubricating all moving parts, especially the guides, and then adjusting the mechanism.

The procedure for dismantling control units for lifts and heating on a VAZ 2110-2112

First of all, use a screwdriver to pry the block off on one side, as is clearly demonstrated in the photo:

Then we lift it up a little so that the power wires become accessible:

Now you can disconnect the power plugs from the unit by pulling each with a certain force:

In exactly the same way, we remove the control unit for heated seats on the VAZ 21102-2112 and replace them in the reverse order.

As for the price of these parts, you can buy a unit for lifts for 800 rubles, and for heating a little cheaper - around 500 rubles.

Schematic electrical diagrams, connecting devices and pinouts of connectors

Electric windows (ESP) are convenient devices for controlling the side windows of a car, which are controlled by a special button and make it possible to lower or raise the side windows without rotating the previously used handles. This option is provided only in some modifications of the VAZ car, but nothing prevents you from purchasing a ready-made unit and installing it yourself.

The most preferred are rack-type ESPs, so as an example we will describe the process of their installation.

Priora window lift diagram

Priora window lift diagram, connection features

Despite the fact that the window lifters are controlled in the same way as on previous models, the design of the Priora's window lifters is somewhat different. There is no power window unit on the Priora. The power windows are controlled by the electrical package controller. This was done for ease of control of electric windows.

To completely open and close the glass, you no longer need to hold down the key, but simply press it briefly. If you hold the button for a while, the window lifter will work until the button is released. The buttons in this case do not switch the circuit, as on previous models, but are a kind of sensors for the electronic unit.

Connecting the driver's door power windows is somewhat different from the connection in the passenger doors. This is due to the use of an all control module in the driver's door.

When you turn on any button on the block, a corresponding signal is generated from it, which is transmitted to the electrical package control controller via the wire connecting pin 5 of the driver's door block with pin 5 of block 3 of the double-glazed window control unit.

When troubleshooting without using diagnostic equipment, you can check the integrity or short to ground of the wire through which the signal passes and the presence of power on the driver's door module unit.

In addition to the use of electronic units in the Priora window lifter circuit, there is a feature of supplying power to the electric drive. One of the wires is multifunctional and is involved in supplying power to the heating and mirror control, as well as to the door lock solenoid.

Therefore, this wire can have either a plus or a minus, depending on which consumer is turned on. The value is controlled by the electrical package controller. On the right and left sides of the wire, pins 4 and 6 are connected separately to connector X1, respectively.

This property can be used to troubleshoot a circuit.

What to do if the VAZ-2114 window lifter does not work

Priora power window diagram troubleshooting

How to find a fault in the Priora power window diagram if the passenger door power windows do not work? A malfunction of the power windows of all doors is unlikely and the reason for this will most likely be a malfunction of the electronic control unit for the power accessories.

A malfunction of the electric lifter in one of the doors is a very common breakdown, especially on early cars. And it is again associated with a malfunction of the unit, and in particular the burnout of the microcircuits that control the operation of the electric drive. The reason was a flaw in the circuit design by the manufacturer.

For the same reason, the window lifts could work jerkily. Subsequently, the block manufacturer corrected the defect, but failure of the block is still the main malfunction at the moment.

It is best to start troubleshooting by checking the functionality of the door lock on which the lift does not work. If the lock also does not work, then you need to check the presence of power or negative on the wire from the glass unit control unit, connector X1, pin 4 or 6, depending on which side you are looking for the fault.

To do this, connect the test lamp to the car body and turn on the power window in one direction or the other. Then connect the test lamp to the positive wire and repeat the operation. It is also worth checking conclusions 1, 5, 11, 13.

If the control lamp lights up in all cases, then the control unit is working properly and most likely there is a broken wire on the door or a malfunction of the electric drive. To check, you need to remove the door trim and connect a test lamp between the wires going to the electric drive.

If the foot lights up when you turn on the lift, then the electric drive is faulty, otherwise the wire is broken. If the unit malfunctions, it is necessary to find out the cause. This could be not only a manufacturing defect, but also a short circuit between the wires or to the housing.

Design features of window lifters "Tens"

What is the electric window circuit in the VAZ 2110, for what reasons does the engine or the SP control unit not work, how to replace it and how to connect the device? First, let's look at the design features of the joint venture, which may vary depending on which specific doors they are used in.

Despite these differences, joint ventures for the most part consist of identical elements; let’s look at the example of electrical systems:

Gear motor or drive. Taking into account the electrical circuit, this device provides the signal necessary to raise the glass.
Grooves. These constituent elements are located on the inner surface of the door frame. The main purpose of the grooves is to hold the glass in a certain position and prevent it from tilting.
Rails. Rails are used as guide elements used to move glass. These components are installed in the door body.
Lifting mechanism with gears.
Seal. The rubber seal allows you to limit the movement of the glass up or down.
Wiring. Its diagram may differ depending on the type of joint venture, but in any case, it is through wiring that signals are transmitted from the control unit to the gear motor.
The control unit itself has buttons that transmit an impulse about the need to open or close the glass.

Causes of malfunction

So, we gradually approached the issue of malfunctions. What if the window regulator cannot go down or up? Before you remove the window regulator, disassemble and repair it in your car, let's look at the main reasons. If the rear or front windows do not work, the reason may be either electrical or mechanical.

Electrical faults

First of all, if the window regulator has stopped working, it is necessary to diagnose the safety element responsible for the functionality of the system. If you realize that the power window is not working due to a fuse, then you just need to replace it. But if the fuse is working, then you will need to measure the voltage at the electric motor terminals. This task can be accomplished using a regular 12-volt lamp or using a tester.

If you find that the driver's window or any other door does not work due to voltage, then you need to further check:

wiring;
relay;
system control unit.

Sometimes a car owner thinks that the window regulator is broken if, after opening the window, it automatically begins to close until the key is turned in the ignition. As a rule, in this case the problem lies in the contacts, which should be cleaned. Much less often, but it still happens that repair of electric windows includes replacing or repairing a button.

Mechanical defects of the mechanism

If, after measuring the voltage, you realize that there is current in the system, but it does not go down or the window regulator does not work at all, most likely the problem is mechanical. As a rule, in this case, something is interfering with the device, so you will have to disassemble the door and look for the reason. Much less often, the reason lies in a failed electric motor (the author of the video is the channel In Sandro’s Garage).

How to raise the glass if the electric seal is broken - there are several options:

Purchase a window regulator repair kit and repair the device, after which you can fully use the system.
Try to grab the glass on both sides with your hands and pull it up. If the glass falls after being lifted, you will have to disassemble the door and place a support of the appropriate size under it.
If you can’t lift the glass with your hands, you can take a fishing hook on a fishing line and lower it into the door card. You need to try to pry the glass and lift it.

Kinds

A window lifter is a device used to move window glass and hold it at the desired point. Currently, the range of window lifters is quite wide, it includes not only many brands, but also differences in target orientation:

front doors
rear doors
left doors
right doors.

Moreover, the design for each device will be different. But in each of the listed cases there are common points; each window regulator consists of:

grooves installed on the inside of the door frame, the purpose of which is to hold the glass sheet at a certain point
“rails”, which are statically fixed in the door body and act as guides for the movement of glass
seal, damper, made of soft rubber, limiting the movement of the glass sheet up and down.

In addition, any type of window regulator consists of two main components:

lifting mechanism
drive unit.

There are two types of drive:

Mechanical - consists of a simple set of parts, a pair of gears and a handle. In order to set the glass sheet in motion, you need to turn the handle clockwise (if you need to raise the glass) or counterclockwise (if you need to lower it). Physical forces are transferred to the drive roller, that’s the whole principle of operation of the mechanical device.
Electrical is a more complex set of parts. An electric window regulator consists of a drive drum or gear and an electric motor with a built-in worm-type gearbox.
