Window lifters VAZ 2110: removal, installation, repair.

The most common causes of malfunction

Window lift repair

On a VAZ 2110, it is advisable to regularly lubricate the velvets with silicone or a penetrating lubricant such as WD-40. Poor glass movement can cause the window lifter to skew during operation, as well as failure of the electric motor due to overload caused by friction forces.

Often the cause of a VAZ window regulator malfunction is directly related to the electric drive. The main problem is the commutator brush mechanism. The brushes may become skewed or stick. In this case, just knock on the door in the area of ​​the electric motor.

Window lift repair

By the characteristic sounds during operation of the VAZ 2110 window lifter mechanism, you can fairly accurately diagnose its mechanical malfunctions. A characteristic growl or crackling sound heard during operation indicates problems with the motor gears. And crunching sounds hint that the VAZ window lifter cable has become frayed.

Applicability on cars

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.

Electrical faults

Electric window diagram

The VAZ 2110 window lifter circuit includes a control relay, a safety block, a power circuit and a push-button mechanism. In order to localize a fault in the power circuit, we need to check the presence of voltage at the power supply terminals of the electric motor.

If the window lifting mechanism does not work at all, the electrical winding of the drive motor or control relay is most likely burnt out. Due to the electrical overload, it is also likely that the fuse in the car will blow (see the VAZ 2110 power window diagram to determine its number). VAZ power windows may also not work due to a faulty button. In this case, the lift functions, but behaves incorrectly.

The process of directly disassembling the door and removing the glass lifting mechanism from it will not take more than 10-20 minutes. of your time and is extremely easy to implement. First, remove the decorative door trim.

How does the window lift mechanism work?

Agree, sitting comfortably in the car, lightly pressing the button opens or closes the window.

Sometimes you don’t even think about how this tricky window lifter mechanism works.

Let's take a look inside. Any average electric window regulator consists of the following elements:

• drive mechanism;
• lifting mechanism;
• window control unit.

Drive mechanism

It is an ordinary electric motor that drives the lifting mechanism through a clever system of worm and gear drives. But with him it’s not so simple.

Lifting mechanism

The fact is that engineers have come up with several options for lifting devices, or more precisely:

• cable;
• lever;
• rack and pinion

Cable

In the first case, the window lift motor acts on a flexible element - a cable, chain or belt. Actually, this is clear from the very name of the drive type.

The flexible element is secured by a system of rollers inside the car door panel, and is attached to the glass using a plate. Everything is arranged so that the cable can move progressively up and down.

In principle, this version of the mechanism is the simplest and most maintainable.

Lever

Lever devices are popular with those automakers who value compactness.

The main operating link of the mechanism, as you might guess, is a lever (one or more) connected to the window lift motor through a gear.

One of the disadvantages of the lever system is the uneven speed of glass movement.

Rail

You would think that the rail would somehow move inside the door, but that is not the case. In fact, the rail is stationary, and the electric motor itself moves along it, having contact with the glass. It is believed that such structures are the most durable.

Window lifter control unit

I would also like to mention the control unit. In the simplest case, this is the so-called direct control, when the button independently connects the motor to the on-board electrical network, activating it.

By changing the polarity of the connection, the direction of rotation of the motor changes - everything is elementary.

A more complex option is electronic control. Electronics allows you to implement various interesting “goodies”, for example, automatic opening, reverse glass movement, etc.

Thus, dear readers, we have found out how the window lift mechanism actually works. As you can see, everything is quite simple, and now there is one less mystery in the car.

Removing the decorative door trim of a VAZ 2110

Before directly repairing the window regulator, you will need to remove the decorative door trim, for which it is recommended to follow the following sequence of actions:

1. 1. Unscrew the lower door pocket, held in place by three self-tapping screws, and remove it from the grooves;
2. 2. If a speaker is attached behind the panel, unscrew it too and disconnect the power terminal block;
3. 3. The VAZ door handle is secured with two self-tapping screws hidden under a removable trim;
4. 4. Unscrew the door latch. Now the plastic decorative trim of the VAZ door is held in place only by latches around the perimeter, which we consistently undermine.

At this point, the first stage of door disassembly can be considered completed.

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.

Switching diagrams for electric windows VAZ - 2109

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.

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.

Connecting electrical equipment

Now, in order for the power windows to work correctly, you need to connect them. If you are not confident in your abilities, then seek help from an experienced electrician. If you are confident in yourself, you can begin installation. To do this, choose a place to install control buttons. It is advisable to place them where there is easy access to them for both the driver and the passenger. Therefore, the best places for installation are the niche under the handbrake, as well as in the beard of the front panel.

After installing the buttons, it is necessary to lay wires from them to the power source through the VAZ-2110 fuse box. It has several backup sockets with which you can connect power windows. Wires are routed from the electric motors in the doors to the body pillar, and from there to the control buttons. It is imperative to use electromagnetic relays to save buttons from switching high current.

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.
