The window regulator ("Kalina") does not work: possible breakdowns and their elimination

Today, very often in the courtyards you can see the domestic "Kalina" from "AvtoVAZ". These cars are very popular among the people, although they often criticize them for the quality of the assembly. As with all foreign and domestic cars, each series has its own diseases - for example, the window regulator is not working. "Kalina" is no exception, so it is important to know the reasons for such annoying breakdowns, and also be able to eliminate them.

Typical causes of malfunction

A power window is a useful thing. Its breakdown can be associated with a variety of different causes. All these reasons are divided into problems with the electrician or various mechanical breakdowns. And the first, and in the second case, the repair of the window regulator ("Kalina" is no exception) can be performed independently in the garage.

Electrical faults

The first and most problem with the operation of window lifts is the hanging of brushes in the collector of the electric motor, by means of which the mechanism of raising / lowering the glasses is set in motion. This happens due to the fact that during the operation of the electric motor brushes from graphite overheat, and the plastic socket in which they are installed from the high temperatures melts. This leads to the fact that the brushes simply stick to the plastic socket. Since AvtoVAZ does not want to give up plastic and replace the nest with a metal one, it will be necessary for the car owners to complete this construction. Under the influence of high temperatures, when the brushes adhere to the walls of the plastic socket, they lose their mobility. When the parts are already slightly worn, they do not reach the collector plates. The spring can not move the adhered brushes from their seats and does not press them to the collector. This fault can only be rectified by mechanical intervention. According to the owners, the repair of the window regulator ("Kalina") is to dismantle the door trim and disassemble the motor itself.

Check the fuse

Another common cause of problems with the operation of the lifting system is associated with the heavy load experienced by the contacts on the common window control panel. Since the specialists of AvtoVaz did not provide for the unloading relay in the electrical diagram, the panel can not withstand these loads. As a result, both the front windows and the rear ones are denied. In this case, the owner will have to fix the problems in the console. If the window regulators have refused to perform their functions immediately from all directions, then it is recommended to check the integrity of the fuse at 30 A. It should be searched under the hood, in the mounting block. If this element is burned, then you will see a dark place where there was a short circuit. It will also not be superfluous to check the insulation of the wires. At the same time, you should pay special attention to the wires in the places of transition from the body to the door.

Is there tension?

It is also necessary to check the presence of voltage on the terminals of the electric motor, which activates the mechanism of the window regulator. Often this node fails due to a lack of voltage. If there is no electricity, you need to look for a circuit break. Typically, the fault should be sought in the control unit and relay. Also it is necessary to clear the contacts of the control panel. Often for this reason, the "Lada Kalina" car does not have a power window (right or left).

Defects in mechanics

What can interfere with the correct operation of the electric motor? It is recommended to inspect the drive shield. If the glass begins to react to pressing the button only after tapping on the door, then the flap sits. To fix this, remove the casing, as well as the rotor and clean these parts with sandpaper.

If, at the touch of a button, the driver hears a characteristic growl, and the glasses do not move, then the plastic gear of the reducer has worn out. Repair here is impossible - just a replacement.

Another reason why the window regulator does not work ("Kalina" -universal is no exception) is the ingress of moisture into the door and the oxidation of mobile systems. As a result of oxidation, the mechanisms are jammed.

If a very loud noise is heard during the movement of the glass, then it is necessary to replace the bearing of the reducer. If, when trying to close a window, the glass twitches, then it is skewed, or foreign objects have fallen into the roller.

It also happens that the mechanism does not work even after the replacement of the electric motor. Then the problem is hidden in the cable. It should be replaced. For the car "Lada Kalina" the replacement price will be approximately 300-400 rubles, as this cable is not sold separately.

Solve problems with the electrician

The first step is to prepare a set of tools. You also need a tester. It is recommended to find a spacious place in advance - in the process of work it is necessary to turn around the car. Now you need to determine the broken glass.

Fuse test

On the left side of the steering column is a hatch that should be opened. There is a mounting block with fuses in it. To open the unit, it is enough to lightly screw it with a screwdriver.

In it, you need to find a fuse with the label F2. It is he who is responsible for the operation of the electric chain of double-glazed windows. There are two options here - either the fuse burned out, or it's whole and then it's worth looking for the problem elsewhere.

Remote controller

If the fuse is still whole, and the glass does not rise or fall, you should go to the control panel on the driver's door. With the help of the same screwdriver, remove the plastic cover - beneath it, the board that you need to reach. There is a switch on it - it is recommended to check the terminal fit, as well as the integrity of the wiring. The problems of this console will explain why the rear windows on the "Kalina" do not work. The switch can be checked with a tester, and if it is defective, it must be replaced.

Wiring

If the switch is working, then go to the next step. For this, the door trim is dismantled, depending on which side of the power window does not work as it should. After dismantling, the double-glazed windows will be visible, with also a mechanism and a motor with wires.

The main goal now is to check the wiring and the electric drive using the tester. It is not necessary to disassemble the motor - everything is easily done with a multimeter. If the engine fails, then it is recommended to replace it. For the car "Lada Kalina" the price of such a replacement will be 500 rubles.

Often, drivers do not want to clean glass from ice and snow - they use automatic cleaning to make their life easier. Its essence is to lower the glass, and when it starts to enter the door cavity, the layer of snow and ice will be removed automatically. But this is very harmful - the electric motor is subjected to incredible loads, which sooner or later will lead to jamming of the stator or rotor. As a result, the power window does not work.

"Kalina" and replacement of the window regulator gearbox

First you need to purchase a reducer. Now they are sold in the same housing with a motor. The door trim is then dismantled . Experts do not recommend performing this operation in the winter on the street on a frosty day, as the cladding on the "Kalina" is fixed on soft plastic pistons. If the fastener element falls off, you will have to glue it. Then you should turn off the screws and other fasteners that hold the inner opening handle. The wiring harness and the speakers are disconnected.

The next step is to unscrew the glass directly, which is held in the guides. It is necessary to unscrew the four bolts with a key by 10. As a result, the glass will sink to the bottom. Also, remove the curtain, which is fixed to the bottom of the insulating glass unit. The window regulator itself is fixed to 4 nuts on the left and 4 on the right on the rails. The motor-reducer is also held by three nuts.

The unit is dismantled through the technological holes. This is a carriage and two guides. Through the last carried out the control cable control gear. On the rope in two places there are rings fixed on the carriages. The reducer is two parts connected by pins. If the latter are unscrewed, the motor will fall into two parts. In one is located the engine with the gear. The other part is a drum with special grooves.

After replacing the gearbox, you must collect everything in reverse order and you can enjoy the reanimated mechanism. The motor-reducer is inexpensive and its replacement is quite simple.

Before assembly, you must carefully inspect and lubricate the cable. If the driver's window does not work on the "Kalina" car after that, then it is recommended to check the amplifier tube. For the glass to fall completely, shorten the rubber bumpers.

Replacement of gears

If the window lifter willingly descends, but refuses to go up, then the gears will need to be replaced. The first operation is the removal of the upholstery together with the switch box. Then unscrew the three nuts that hold the geared motor. Then turn off the nuts securing the mechanism and the bolts securing the glass, do not forget to detach the shoe. Then the reducer is removed directly, the self-tapping screws are loosened and the lid is removed. Using a screwdriver, the gear is removed and its housing must be thoroughly cleaned. The bearing, as well as the worm, should also be carefully lubricated. Then everything is assembled in the reverse order.

If the window regulator is not working (the Kalina hatchback is no exception), then after such a replacement it will work, because the gear is one of the typical reasons for the failure of the mechanism.

In the event that all these measures have not helped, then the whole mechanism is changed completely together with the motor. The dismantling is not so difficult, the main thing is to buy a high-quality mechanism. Spare parts on sale may differ from those that are installed in the factory.

Cost

How much does a new window regulator cost for Kalina? The price of the original mechanism is 1500 rubles. You can also buy analogues. For example, the motor of the glass elevator of the company LSA can be purchased for 500 rubles.

Conclusion

So, we have found out the reasons why the window regulator on the domestic car "Lada Kalina" does not work. As you can see, even a novice motorist can solve this breakdown. In this case, spare parts for the "Kalina" can be found in any area of your city.
