Lada granta power window switch block repair

Restoring the power window button

An electric window regulator (ESP) is a car device that allows you to raise and lower the door windows using a button. The ESP consists of a drive mechanism, a lifting mechanism and a control unit.

Like any other systems subject to intensive use, electric windows have an increased service life - about 30 thousand opening/closing cycles.

This resource is sufficient for 10 or more years of uninterrupted operation, however, if handled carelessly and/or under the influence of other negative factors (for example, water ingress), the device may fail much earlier than the stated period.

Most often, problems arise in the mechanical part, that is, some part of the lift itself breaks. In this case, when you press the button, you will hear the sound of a running motor, but the glass will remain in place.

It is worth inspecting the lifting mechanism for damage to the guides along which the glass moves.

To fix this problem, you will have to replace the entire mechanism, since parts are rarely sold separately.

If the ESP electric drive itself at one point suddenly stops responding to the press of a button, you should not rush to a car service center.

In this case, you can repair the power window yourself. You should start by finding the cause of the problem, and there may be several of them.

Here are the most common:

The fuse has blown. If any electronic device in your car stops working, you should first look at the fuse box;
The wires have broken or the contacts at the terminals have become loose. In this case, it is enough to restore the connection;
The drive motor has failed. In this case, it will need to be replaced;
The button itself is broken. If the driver's door power window button does not work or works intermittently , but the window rises properly from the main control unit, then the problem is in the button itself.

The most common problem with ESP buttons on cars of any brand is oxidation of the contacts.

Due to constant temperature changes, a layer of oxide forms on the copper plates, which is why the button first starts working once. To fix the problem, you need to disassemble the control unit and clean the contacts from traces of dirt or oxidation.

It should be understood that any cleaning gives a short-term effect; over time, the problem will certainly recur. For greater reliability, it is recommended to replace the button.

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.

Detailed design of the EP system

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.

How to remove and connect the window lift button - using the example of LADA Kalina/Priora

Repairing the window lifter button on Kalina, Priora or Grant is not difficult. And no serious financial costs will be required, since the price of the “native” passenger door button is only 150 rubles. The cost of the control unit on the driver's door is about 600 rubles.

To remove the button on the passenger door or the control unit, you do not need to remove any decorative trim or door trim. There is no need to look for screws to unscrew them, since there are none.

It is enough to carefully pick up the button or block with a flat screwdriver and simply pull it out of its seat. To avoid accidentally scratching the casing, it is recommended to wrap the screwdriver in a thin cloth.
Then you need to disconnect the wire terminals to completely free the power window control module. Next, you need to tightly connect the terminals to the new button and return it to its place.

Procedure if the window regulator does not work

1. In the mounting block, check the power window fuse (F2, 30A) and the power window relay (K2).

2. Remove the door trim and check the voltage at the motor terminals using a multimeter or a 12V test lamp.

If there is no voltage, then check the serviceability:

power window buttons
wiring (connector connection)
electrical package control unit (central body electronics unit), which is installed on “luxury” vehicle trim levels
central locking unit

If current flows to the motor, but the glass does not move, then there may be several reasons:

malfunction of the window lift motor (for example, the drive motor brushes are stuck/sticking, the plastic gear in the gearbox is worn out)
The window lift cable is frayed
glass is jammed (distorted)

According to the results of the survey “what was the cause of the malfunction of the power windows,” it turned out:

in 50% of cases the problem was in the window lift motor
in 22% the reason was in the power window cable
the remaining 28% were divided into parts (glass distortion, faults in the power window button and wiring)

How to remove the power window button on a grant

Electric window switches are installed in the door trim. A block with switches for all electric windows is installed on the driver's door. Depending on the configuration, some vehicles may have power windows installed in the rear doors.

To remove the switches, it is advisable to dismantle the door trim, since if you try to remove it by prying it with a screwdriver, there is a high probability of damaging the trim and the switch itself.

The operation is shown using the example of a switch block on the driver's door. Removing and installing the power lift switch on the passenger door is performed in the same way.

1. Remove the door trim

2. Squeeze the two latches.

and remove the power window switch block.

You can check the switch with a multimeter in ohmmeter mode. The switching of the switch terminals is shown in the general diagram of the electrical equipment of the car.

Lada Kalina window lifter does not work (Repair)

Another main disease of the Lada Kalina is electrical equipment. Everything breaks completely, from the electric power steering to the power windows. Now we will tell you how you can repair the power windows on a Lada Kalina with your own hands .

Even before winter, the left window regulator of the driver's door began to damage my brain. To be more precise: it goes down, but it comes up with problems. With jerks and sometimes with mechanical force, he helped with his hand. And now the time has come to replace it or rebuild it. I was hoping for the latter. I bought two gears in advance, but didn’t know which one would be suitable.

Lada Kalina window lift repair:

1. The first thing we do is prepare the car, tools and components for repairing the power window.

2. Next, remove the door trim ( photo No. 1

), after removing the switch block.

3. The next thing we do is unscrew 3 pieces of M6 nuts securing the gearmotor. ( photo No. 2

)

Operating principle of electric windows

The electrical control system, as a rule, has a trapezoidal design that ensures easy lowering and raising of the windows when the corresponding buttons are pressed on the main switch block, which is either located next to the driver or is embedded directly in the door panels. An independently functioning motor is installed inside each door, which is capable of working in two directions, raising the glass up and lowering it down.

The power window system on modern cars includes special relays that control the electric current going to the window motors.

On some machine models, in addition to the fuse that protects the entire circuit, there are circuit breakers designed for each of the electric motors separately.

The introduction of such an element guarantees proper operation of the entire system of electric windows in the event of failure of one of them.

How to remove the module and control unit for power windows for 2 and 4 windows: how to remove the panel, repair

Power windows (ESP) are now installed on many modern cars. The normal operation of the ESP depends on the performance of all component elements of the system, in which the power window control unit is considered one of the main ones. What is the principle of operation of the device and what malfunctions are typical for it - we will discuss this below.

Description of the power window control unit

What is the glass control module used for, what is its operation scheme, and in what cases is the system repaired? First, let's look at the purpose and operating principle of the device.

Purpose and device

The module itself is controlled using buttons located on the panel in the car interior, or by an anti-hug system if the ESP is supplemented with closers. If the latter are present, when the car owner sets the vehicle to security, the device automatically closes all windows completely. If the closers are multifunctional, then when the car is further opened, the windows will return to their original position. The module is equipped with buttons with which control is carried out.

If necessary, the car owner can block the control buttons on the panel, thus preventing the windows from opening and closing unnecessarily.

We invite you to familiarize yourself in detail with all the functions that the control unit performs:

Controls the windows, as well as the sunroof, if available, if necessary or when the car alarm is activated.
If we are talking about door closers, the driver will be able to configure the system in such a way that even when the alarm is turned on, the unit does not completely close the windows, which will ensure ventilation of the interior.
The device will block the movement of the glass if necessary, for example, if the device encounters an obstacle while driving.
If the unit has a movement blocking button, the driver can press it to block opening or closing. This is especially true if there are children in the vehicle.
If the cable breaks during operation of the ESP, the module will automatically block the operation of the system and turn off the electric motor.
In addition, the system will shut down if a short circuit occurs in the operation of the electrical circuit or motor.

Operating principle

As for the principle of operation, in general the system works according to a fairly simple principle. Voltage is created on ESP electric drives by pressing control buttons. Two wires are connected directly to the mechanism itself - blue and gray. When voltage is applied to the blue wire, the glass rises, and when voltage is applied to the gray wire, it lowers.

If the system uses closers, then first the impulse goes to them, and only then to the motor with the relay. Accordingly, if there is a closer, the system is supplemented with another module. All communication mechanisms

A simple way to increase the speed of the windows on a VAZ:

DC power supply with a voltage of 12V and a current of no more than 2.5A;

The glass lifting time is no more than 5 seconds;

Nominal lifting force 120 N;

Noise level 40 - 50 dB.

In order to unify and reduce the cost of the people's car, the designers of OJSC AvtoVAZ retained most of the parts (approximately 70%) from the Lada-Kalina car. And the electric door windows were no exception - Lada-Granta cars are equipped with an electric drive for raising and lowering the front door windows, which is completely similar in design and execution to the mechanism previously installed on Lada-Kalina cars.

If in previous VAZ models, on which a mechanical window lifter was installed, the usual gear reducer was used, then on the VAZ 2190 model there is only a drum with a hole into which the output shaft of the gearmotor is pressed.

The gearmotor itself is structurally made of a direct current electric motor, excited by permanent magnets and a worm gearbox.

Grant window lifter control unit

Its design is almost completely similar to the design of the windshield wiper gearmotor.

The gearmotor can be called reversible, because The direction of rotation of the output shaft depends on the direction of movement of the electric current in the armature winding. The built-in thermobimetallic fuse protects the gearmotor from overloads.

The schematic electrical diagram of lifts with electric drive of the Lada Granta is shown in the figure.

Here, gearmotors 2 and 5 are powered through switches 3 and 4, which are mounted in the armrest handles. Voltage to the switches is supplied from contact “2” of the immobilizer through the contacts of relay K2 located in the mounting block and fuse F2. Relay K2 is a relay type 904.3747-10.

Removing the power windows

Let's start with the front mechanisms

Before proceeding with repairs, it is necessary to dismantle the defective device. But in order to remove the window regulator, you will first have to remove the door trim.

So, for work we need:

key for 10
molar tape.

Now let's get down to business.

The first step is to lift the glass all the way and secure it at the highest point with tape.
Then, using a wrench, remove the two bolts that hold the glass in place (1 in the picture). Also, you need to unscrew the bolt of the inner handle of the lock.
The next step is to disconnect the device motor and wires (2 in the figure).
We unscrew all the nuts on the device (there are 11 of them in total) and remove the window regulator (2 in the figure).

How to remove and connect the window lift button - using the example of LADA Kalina/Priora

To remove the button on the passenger door or the control unit, you do not need to remove any decorative trim or door trim. There is no need to look for screws to unscrew them, since there are none.

It is enough to carefully pick up the button or block with a flat screwdriver and simply pull it out of its seat. To avoid accidentally scratching the casing, it is recommended to wrap the screwdriver in a thin cloth.
Then you need to disconnect the wire terminals to completely free the power window control module. Next, you need to tightly connect the terminals to the new button and return it to its place.

Replacement of front electric windows of Lada Granta

You will need : a flathead and Phillips screwdriver, a 10mm wrench and remove the front door trim.

Front ESP mounting diagram:

1. glass guide fastening nut; 2. nut for fastening the gearmotor; 3. glass holder bolt; 4. block with electric drive wires.

First you need to remove the Granta door glass ; to do this, you need to lower it to its lowest position. Further:

Remove the door trim mounting bracket by removing 3 bolts.
Remove 2 bolts (according to diagram No. 3), holding the glass.
Remove the front door glass by lifting it up and turning it in the door opening.

To remove the Lada Granta power windows you need:

Unscrew the 8 nuts securing the glass guides (No. 1 according to the diagram), as well as the 3 nuts securing the window lift motor to the inner door panel (No. 2 according to the diagram).
Remove the window lift mechanism assembly with the gear motor from the door cavity.
The photo shows the assembled ESP Grants.

Installation of window regulators is carried out in the reverse order.

Procedure for removing rear power windows

First of all, you need to figure out how to remove the trim from the car doors and do it. Also prepare keys with heads “10” and “8”. Now you can begin the process of disassembling the rear windows.

Fix the rear door glass and gain access to the glass mounting bolts. Using a 10mm wrench, remove these bolts.
Using a key with an “8” head, unscrew the three elements securing the ESP to the door.
Using a “10” wrench, unscrew the two nuts securing the window lifter guide.
Remove the ESP itself.

Installation of the rear window regulators is carried out strictly in the reverse order.

Mechanisms for rear windows

When reassembling, it is necessary to take into account that when placing rivets on the door trim, you need to ensure its reliability and protection. The dust and moisture protective film should not have folds or tears. Everything that is installed must be in perfect condition. The ground wire must be connected to the battery. After this, the electronic system should be fully initiated.

Installing or replacing a window regulator is not difficult for any Priora car owner, but to install this unit correctly, you need to be patient and prepare the required set of keys.

The ESP kit always has a manual available, which describes in detail the sequence of work for installing the device.

It is important to know how to remove the terminals from the battery. The existing set of wires must be assembled into a common harness to connect to the machine’s network. On the back of the fuse box, find the standard hole and insert the wiring harness block into it. Then everything goes according to plan.

How to fix stuck power window buttons on a Priora

If the power window buttons work every once in a while or get stuck , but at the moment it is not possible to purchase a new control unit, you can fix the problem as follows:

We remove the control unit. To do this, you need to carefully snap off the 6 plastic clips on the body of the decorative cover;
Let's disassemble the block. To do this, you also need to unclip 6 clips on the body of the unit itself;

How to remove the window regulator on a Priora

Despite the fact that the principle of controlling the window lifters is carried out exactly the same as in other models, the Lada Priora car uses a slightly different window lifter scheme . The main difference from other models is the absence of a power window unit. They are controlled by an integrated electrical package controller. The designers made this design to ensure ease of control.

To fully open and close the window, the driver does not need to hold down the control button. All that is required in such a situation is to hold down the button for a certain time. If you do not meet the specified time period by releasing the key too early, the window regulator will stop raising or lowering the window. In this case, the buttons do not cause network switching, as on a number of other models. They perform the function of a sensor, transmitting information to the electronic unit.

In addition to the use of electronic units, the operation circuit of the Lada Priora 2014 car windows supplies power to the electric drive in a specific way. One of the wires available in the system is multifunctional. It can control the mirrors, supply power, and also control the door lock solenoid.

Consequently, this wire can change polarity, depending on the characteristics of the switched-on consumer. The wires on the left and right sides are connected separately to connector X1. In this case, pins 4 and 6 are used. This property is very useful when locating potential circuit faults.

You may also need advice about Lada Priora error codes, which will help you identify a malfunction in your car.

How to look for faults in the current circuit of a Lada Priora car if the passenger door windows stop working? All power windows are unlikely to break at once. If you had to encounter such a breakdown in practice, most likely the problem lies in the electronic control unit for the electrical package.

It is worth noting that the breakdown of a single window regulator is very common in practice, especially on cars of the first production. The reason, again, is a malfunction of the unit, when the circuits responsible for controlling the electric windows completely or partially burn out.

This is due to shortcomings in the circuits by the manufacturer. The same reason could cause the window regulators to operate jerkily. As a result, the block manufacturer completely eliminated the problem, but this did not improve the situation, since older models still suffer from this “disease.”

But you shouldn’t hope that all the problems are just a (to put it bluntly) unstable block. Moreover, you should not believe that replacing the control module will correct the situation. There are a number of other reasons why malfunctions may occur.

Main causes of failure

Most likely the power window fuse is at fault.

The angle is not good, but this is exactly what the mounting block looks like when you look at it from above

From the situation you described, it follows that the fuse is to blame. There are enough symptoms and prerequisites for its breakdown. First, you raised one glass, which is already good, since raising both windows at the same time is not recommended due to the increased load. Then they started to lift the second window, and the fuse burned out.

F2 (30A) - fuse number in the mounting block.

If one of the glasses works, then the fuse is good.

The button is broken

The power window buttons in the Norma configuration usually do not cause problems

If only one of the two or four power windows does not work, depending on the configuration and equipment of the car, then the problem is most likely in the button or in the wiring to it. It is necessary to remove the front door trim and ring the buttons, you can also look at the voltage on them.

Motor failure

The window lift motor on the Lada Granta rarely causes problems. This part is reliable, but it can also fail. You can check the motor by applying voltage to it forcibly, that is, directly from the battery.

The power windows of the Lada Granta do not work, why?

Car: Lada Granta. Asks: Evgenia Kislyakova. Question: The glass went down, but didn’t go back up, what happened to the window regulator?

Good afternoon. I stopped in the parking lot, raised the right passenger window all the way, began to lift the left one, and it stood in the middle. I had to put Grant in a friend’s garage; I was afraid to put it in the parking lot in case it rained or a bird flew in.

Two front windows broke at once. I don’t have electrics at the back; the windows are lowered and raised using handles. When I press the power window button, nothing happens. I tried it with the machine turned on too.

If the buttons are working properly and the fuse is intact, then you should contact an electrician. Or you need to “ring” the wires yourself and look for where the break is.

An absolutely similar situation happened to me, I even fell into a stupor at first. I went online and read this article, called an electrician I knew, he “ringed” the wires and fixed everything. Thanks for the advice, you don’t always immediately know what to do.

Yesterday I had this unpleasant situation. I was looking on the Internet for a solution to the problem and came across this article. I called a friend, he fixed everything as written in the article.

I had the same situation! Last week, when I was out in nature with my family. At first I thought maybe the nephews were to blame, well, they are small, playing with the window regulators... And then the eldest daughter looked on the Internet and showed your article. Well, then I understood everything and went to the nearest salon... They did everything well, and they also said that I was not the first Lada Granta driver to come to them with a similar problem... Are there really such defects in many cars?

The window lifters were not working well, I puzzled over this problem for a long time, I decided to lubricate the window lifter motor with machine oil, which helped.

I am a novice driver, and when such a disaster happened, I decided that I would do it myself and started looking for videos and articles with a detailed description. And then a miracle happened. I studied everything and went to the garage to my Lada Granta. I got it done, I won’t say it was quick, but I did it all

I had the same problem, the window regulator stopped working. There was a problem with the button, the copper plate there burned out. I changed the button and everything worked.
