Window lift motor VAZ 2110 - replacement and repair

Today, the domestic “ten” continues to confidently remain in a leading position among the most popular cars in the country. They have already stopped producing them, but this does not stop many people from driving a VAZ 2110.

The car is far from ideal, but it has a lot of positive qualities. One of them is the simplicity of the design, which allows you to perform a whole range of repair work with your own hands.

An example of a successful design that combines good reliability and the possibility of self-repair is window regulators.

Kinds

Window lifters are devices that serve to move glass on windows and hold it in a given position. Today, the VAZ 2110 is available with quite a variety of window lifts, which differ not only in manufacturer, but also in purpose.

If we take into account the purpose, then devices can be divided into four types:

• For front doors;
• For rear doors;
• For left doors;
• For the right.

It is noteworthy that their design may be different, but they have quite a lot of common nuances.

Any of the listed window regulators includes several main components.

The design of any window regulator includes two main components - the drive and the lifting mechanism.

Drives

As in many other cars, in the case of the VAZ 2110 there are two types of drives.

1. Electric. A rather complex set of elements, which consists of a drive drum or gear, as well as an electric motor with a worm gearbox built into it. This design allows you to raise and lower the glass at the touch of a button.
2. Mechanical. The most simplified design, which includes several parts, gears and handles. To raise the glass in a VAZ 2110 using a power window lifter, you need to turn the handle clockwise. The drive roller takes on the required physical effort, so lifting is not difficult.

Lifting mechanisms

As for lifting mechanisms, there are several of them. For the VAZ 2110, various options are available.

Rack and pinion mechanisms

Electric glass lift

Rack and cable mechanisms are offered complete with electric and mechanical drives, while lever mechanisms are available only with an electric motor.

Electrical problems

Do-it-yourself camouflage on a car
It is better to start diagnosing a malfunction by checking the condition of the fuse, which is responsible for the operation of the power windows in the VAZ 2110. Usually it is numbered F5. If necessary, the fuse must be replaced with a new one. If it is intact, proceed to the next stage. You will need a 12 volt light bulb with two wires going to its positive and negative side.

Connect the wires to the terminals of the window lift motor and press the button. If the light comes on, the wiring is good, but if not, start looking at the wires for breaks. Also don't forget to check the corresponding relay.

Another problem with the electrical wiring circuit is when the window opens when the button is pressed, but when it is released the glass rises again. In some cases, the button does not work until you turn the ignition off and on. These signs indicate a malfunction of the button, so you can try to remove it and clean the contacts, and if necessary, replace it with a new one.

Replacement

The need to replace or repair window regulators may arise for two main reasons. Namely:

• The old gears of the lifting mechanism are worn out, due to which the device ceases to perform its functions;
• The cable broke, which caused the entire system to fail.

Disassembled structure

To solve the problems that arise, you will need to go through three or four steps:

• Preparatory activities;
• Dismantling;
• Installation;
• Repair.

If you plan to simply replace the mechanisms with new ones, then you can skip the repair stage.

Although versions with mechanical and electric windows are available for the VAZ 2110, the nuances of the replacement procedure will be identical. Therefore, the instructions below are relevant for both cases.

Preparation

To begin with, we will talk about the preparatory activities that will allow you to get to the desired mechanism. There is nothing complicated here if you follow the instructions.

Although the front, rear, left and right window lifters are structurally different, the principle of working with them when repairing or replacing is similar.

1. First, remove the glass lift handle. To do this, remove the stopper, which you will find under the lever washer of the handle. Using a screwdriver, the latch is moved to the side, and the stopper is removed from the plate. After this, the handle can be easily removed. Sometimes it can get tight, so take a second screwdriver and pry the device up onto the base.
2. Next in line for dismantling is the armrest handle. You will need a flathead screwdriver to unscrew the plugs covering the pair of mounting screws. They are the ones that hold the armrest handle. Armed with a Phillips screwdriver, the screws are unscrewed and the handle is removed.
3. Now we move on to the handle of the exterior rear view mirror, plus the handle trim is dismantled.
4. At the last stage of preparatory activities, you need to remove the door trim. It is held on by plastic pistons. If they are damaged, you can always buy new ones. Don't forget to also remove the storage compartment.

Dismantling

The preparation is complete, so you can begin to directly dismantle our failed window regulators.

• Lower the window completely. This will allow you to get to the fasteners that connect the glass panel to the window regulator device. The device is held in place with a pair of bolts. To unscrew them you will need a 10 mm wrench;
• Next, decide for yourself what is more convenient for you to do. You can fix the glass with tape and continue the repair. Or you can remove the glass completely. The second option is not the most successful, since it will require more effort and time;
• Remove the socket from the slot;
• Using an 8 mm socket, the fastening nuts are unscrewed, which gives you the opportunity to remove the damaged window regulator.

Dismantling works

Installation

The device has been dismantled, so we can talk about several of the most important nuances of reinstalling the power windows.

1. Replace the damaged element with a new one, after which assembly is performed strictly in the reverse order.
2. If at the previous stage you decided to completely remove the glass rather than secure it with tape, then be sure to adjust its position during installation. This is done by displacing the bolts in the mounting holes.
3. During dismantling work, the holders - pistons - often break or suffer. Therefore, before starting repairs, we advise you to purchase a set of new holders so that you don’t have to run to the stores in the middle of the work process.
4. When installing your window regulator handle, make sure it fits snugly in its rightful place. If you cannot fit the handle tightly, use several rolls of electrical tape. This should help.

Power windows

What is molding on a car? How to glue it yourself

Some cars have electric windows installed at factories, but you can also install them yourself.

Power windows device.

An electric drive differs from a manual drive in that it does not have a gearbox. In its place is a drum, which has a square hole in the center. This hole includes the gear motor shaft, which is attached to the mechanism using racks. The design of the gearmotor is standard, an electric motor with excitation from permanent magnets, the armature shaft of which has a worm gear at the end. This gear is part of the worm gear and meshes with the helical gear. The torque from the gears is transmitted to a drum on which three turns of cable are wound. Closing and opening of the glass is ensured by changing the polarity when power is supplied to the electric motor. The electric window lifter of the VAZ-2109 is controlled using a button. To protect against overloads, the gearmotor has a thermal fuse.

If you want to install additional power window buttons on the driver's side, they are not connected in parallel. The corresponding button contacts are connected in series. Below is the connection diagram.

Electric windows, automatic control.

In addition, some cars may be equipped with automatic window lifters. For this purpose, an electronic control unit is additionally installed. Below is a diagram of the electric window control unit type 1903.3763.

The unit switches on the window lift motor for raising and lowering in manual mode, as well as switches on the gear motor for lifting on command in automatic mode based on a signal from the central locking device. The system also automatically stops the electric motor of the gearbox when the glass is in extreme positions when raising and lowering, or when the glass jams during movement as a result of misalignment or foreign objects or hands getting into the gap between the frame and the glass. This is achieved by increasing the current with increasing force when braking the movement of the glass. In this case, a thermobimetallic switch, a reed switch or a switch with a Hall sensor is triggered and the electric motor stops.

Repair

It is not possible to repair window regulators in all cases. Mostly, these glass lifting devices can be repaired in case of obvious mechanical fractures of the elements.

But we can still give some useful tips regarding restoring the functionality of the window regulator without replacing it.

1. If the electric window motor fails to work, then the brushes or winding are most likely to blame. To verify this and fix the damage, you need to remove the motor, disassemble it and clean the outer and inner surfaces.
2. For cleaning, it is recommended to use a lint-free cloth. The cloth is soaked in gasoline, alcohol or a special cleaning agent. When you buy the latter, you can use it for a long time, the efficiency is higher compared to gasoline.
3. After cleaning and drying the parts, it is recommended to treat the moving elements with lubricant so that the mechanisms function longer.
4. If the cable comes off the lifting mechanism, you will have to dismantle it, remove the electric motor, or unwind the cable if it is mechanical. Then the cable is pulled back onto the grooves and the assembly is reassembled.
5. If a malfunction occurs in the mechanism or the electrical circuit of the device, it is necessary to study this circuit, determine the direction of the wires, and then ring them. This is the most effective way to check for electrical failure.

Lifting device diagram

Repairs in most cases only give temporary results, so soon you will still have to make a full replacement. This is due to the fact that each part has its own service life and degree of wear. When they are reached, the window regulator stops working.

Replacing or repairing mechanical or electrical window regulators cannot be called complex undertakings. It is quite possible to cope with such tasks with your own hands.

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.

Replacing the window regulator on the front doors of a VAZ 2110

An article with step-by-step photos and video instructions on how to independently replace the window regulator on the front doors of VAZ 2110, 2111, 2112 cars.

Each window regulator is stamped with the vehicle model number and part number. The last two digits indicate: 10 – right door; 11 – left door.

Device

This drive - the engine - is a familiar motor, with the help of which we tried to carry out certain experiments in physics lessons at school. The motor is remembered for the fact that its force affects the gear reducer. The basis of the mechanism is the anchor. There is a worm that looks similar to the spiral of the meat grinder. When the rotor rotates, the transmission exerts force on the wheel.

This design and characteristics of the mechanism, including the gearbox and other elements, influence the movement of the glass. The window lifter, depending on its type, has its own motor, but this factor often depends not on the location of the winding, but on how convenient it is to attach it to the door plane. The motor itself is equipped with special stickers.

Withdrawal procedure

1. To access the window regulator, remove the door trim.
2. Special bolts are used to secure the glass frame. Lower the glass so that the mounting bolts are accessible through the top hole of the door. You need to unscrew the 2 bolts securing the glass frame to the window lifter slider.
3. Using your hands, lift the glass all the way up and jam it in the upper position.

At the same time, lower the window lifter slider down until it stops.
5. On the front door, you need to unscrew the 4 nuts securing the guide and the 3 nuts securing the window lift mechanism itself.

6. On the rear door, you need to unscrew the 2 nuts securing the guide and 3 nuts securing the window lift mechanism.

7. The window regulator is removed through the technological hole in the door.
