Overview of General Concepts
Installing rear power windows on a Priora is clearly not within the capabilities of every driver who decides to install it themselves or replace a failed device with their own hands. Before installing these devices in a car, you need to have at least approximate knowledge of the operating procedure and the principle of operation of the device itself. Without this, proper repair of the window regulator is impossible. The electric window mechanism is installed inside the doors. Priora's window regulators consist of an electric motor, a drive and an electronic control unit.
In some configurations of the Lada Priora, factory rear ESPs are installed, which does not eliminate the need for knowledge about their design. Replacing a window regulator is a problem that comes up unexpectedly, so it's best to be prepared for it in advance.
As some car owners have found out, in order to install power windows, you need to be able to understand electrical wiring and have a lot of patience. In particular, in the 2008 Priora, it was discovered that the rear door wiring was not completely routed, which seriously complicates the work. In addition, the operation of standard ESPs with the ignition off is impossible, even if you insert a jumper into the desired relay.
There are many sets of rear lifts on sale that are compatible with the VAZ-2110, Granta and Priora. The cost of the kit can reach 3,500 rubles, depending on the type of design and manufacturer. Installation of equipment at the service will cost approximately the same amount. Many VAZ 2170 Priora owners sooner or later face the problem of failure of standard power windows. There are two common reasons:
- Broken cable.
- Electric drive failure.
The work of standard window closers also causes criticism, due to which the car is often left wide open. They also resort to replacing them quite often.
Common faults
Malfunctions of the mechanism that raises the windows can be electrical or mechanical in nature. Regardless of the nature of the breakdown, you can do the repair yourself (video author: Xie Dan).
Mechanical failures can be detected without ignition.
The following are typical mechanical problems:
- wear of the teeth on the device gear;
- sunken shield;
- a defective cable mechanism can stretch or deteriorate, and later during operation it will come off the guide rollers;
- jamming of mechanisms due to oxidation of moving parts;
- gearbox bearing wear.
Mechanical defects of the device
Among the electrical reasons why the power window on a Priora does not work are the following:
- If all four power windows do not work, the first thing you should check is fuse number F31. It is located in the power management mounting block. If the element burns out as a result of a short circuit, it should be replaced. In this case, it is advisable to check all wiring.
- Sticking or sticking of the brushes of the electric drive motor. This happens due to overheating of the graphite brushes, which melts the plastic nest in which they are located. Thus, the brushes stick to their nest and lose mobility.
- No voltage at the motor terminals. The cause may be an open circuit. The fault must be looked for in the relay or control unit. In addition, the contacts should be cleaned.
Fuse block
If the mechanism itself that raises the windows is faulty, then it needs to be replaced.
Types of compatible window regulators
One of the most common models on the aftermarket is the window regulator for the Priora Forward. This model of electric lift is made in a combined arrangement of the drive and the actual rack-and-pinion lifting mechanism, compactly combined with the glass guide. Lifts of this model are characterized by increased reliability and ease of installation on Priora.
Garnet is the second most popular system. Under this name there is not even a single model, but a whole family, each modification of which is intended for a specific car. The mechanism is also rack and pinion type and has earned many good reviews from car enthusiasts. This type of lifts is characterized by uninterrupted operation, fast speed of raising/lowering the glass, and low noise.
It has already been said above about glass closers. In the luxury package they are available on all doors, but their performance leaves much to be desired. It is necessary to resort to replacement with other similar devices. One of the available alternatives is the Master system. It allows you to automatically raise the windows when the anti-theft system is turned on, and even control them within half an hour from the moment the ignition is turned off. The device itself looks like an electronic board with connectors connected to the standard Priora wiring.
The master is not very expensive (from 700 rubles), and its installation does not affect the door trim in any way. The whole procedure consists of removing the rear door sill trims, bending the sound insulation and connecting the door closer to the connector.
For the front doors, the Master will by default raise and lower the windows without ignition, and for the rear doors you need to install a slightly different version, called Master Plus. There are no differences in installation, the main thing is not to forget to disconnect the negative battery before starting work. The wizard has many other useful functions, for example, it automatically turns off the radio when the car is armed.
Installing rear door lifts
Electric windows are a necessary element of comfort. But with Priora everything is not so simple. Standard wiring (unless, of course, you have a luxury version) is not enough to install lifts in the rear doors. And the first thing you have to do is stretch the necessary wires from the control unit to the doors. Moreover, this is not the only difficulty. On some versions without rear ESPs, relays for them are installed, and the control unit has only 2 buttons. Thus, in order to install the lifts back, you need to change the control unit to a four-button one.
Features and diagram of electric lifts
The electrical circuit of the ESP Priora differs from the circuit of previous VAZ models. This vehicle does not have a power window unit. The controller controls the mechanism. When using the device, you do not need to hold the button for a long time to completely open or close the glass. The button is a sensor for the electrical unit, which receives information about the operation of the ESP.
We can also talk about the specifics of supplying power to the electrode in the electrical circuit. The multifunctional wire takes part in the transmission of heating energy and at the same time in controlling the mirrors. This wire acts as a “plus” or “minus” depending on what function it performs. The electrical package controller controls all the values of this wire.
Most often, damage occurs in the electrical unit itself, for example, the control microcircuits of the unit burn out. The reason for this is the shortcomings of the work of the manufacturer’s specialists, the imperfection of the electrical unit system, and its manufacturing shortcomings. The problem is indicated by intermittent operation of the power windows.
You can start troubleshooting by checking the quality of operation of the rear or front door lock. If the lock is not working, you need to check for the presence of a “minus”. Having connected the control lamp to the car body, turn on the window regulator. Connect the same light bulb to the positive wire and repeat everything you did earlier. All conclusions must be verified using this method. If the testing was successful and the light comes on, then the electric window control unit itself is working properly. You need to look for the cause in the wiring: a broken wire on the door or a faulty electric drive is possible. The test will consist of connecting a control lamp between the electric drive bundles.
After turning on the lift, you need to make sure that the lamp lights up - this means there is a malfunction in the electric drive. If the light does not light, there is a broken wire. If it turns out that the electrical unit is faulty, then you need to look for the reason when checking the wires: whether there is a short circuit between the wires or to the housing. Otherwise it is a factory defect.
Some experts recommend installing a power window closer on the Lada Priora, and you can do this yourself.
This article will consider this type of Priora repair, such as replacing the electric window mechanism assembled with the motor. Of course, if your electric motor has failed, then there is no need to change the entire mechanism. Regarding the motor, it will be shown below how to change it.
Necessary tool for replacing the window regulator on a Priora
- 10 mm head
- Extension
- Ratchet or crank
Flashing the immobilizer
As a rule, Priora is equipped with a standard APS-6 immobilizer. This, as already said, is an optional procedure, but if the budget does not allow you to invest in a security system, you will inevitably have to deal with all this electronic “stuffing”. In addition to the power windows, the immobilizer controls several other systems of the car, even the rear lights. But the main problem is precisely that in the Priora car the immobilizer is structurally combined with the glass unit controller.
Priora lends itself well to tuning. A solution was also found for the immobilizer. During learning, the immobilizer writes its code to a non-volatile area of the ECU memory, which is stored in a disabled state. To disable the immobilizer, you need to clear this memory cell in the ECU.
To do this, you need to disconnect the original wiring connector from the immobilizer. Next, you need to determine the type of ECU. The flashing method will depend on this. If it is a Bosch M1.5.4, you need to open it and install a specially prepared chip with a program for cleaning the ECU EEPROM in place of the standard one and turn on the ignition for a few seconds. For some ECUs, you need to download special programmers from the Internet.
You can order flashing from specialists at reasonable prices. By the way, the Priora immobilizer itself is often prone to malfunctions, and therefore you need to interfere with its operation with extreme caution. On some types of ECUs, it is impossible to do without desoldering the microcircuit and you cannot completely erase the EEPROM. We end here. Good luck!

Replacing the window lift motor of Lada Priora
As mentioned above, the most common reason is the failure of the electric motor. And in this paragraph we will consider the procedure for replacing it. First, you need to turn the mechanism over so that the pins are facing us.
- Turn out all three studs
- Using a flat-head screwdriver, unscrew the screws securing the motor housing to the window regulator.
- We separate the two parts of the structure and install the new electric motor in place
I think that there will be no problems with replacing the electric motor itself, since its attachment to the main structure is elementary. If you still have questions, you can discuss them in the comments below or under the video on the channel.
Instead of introducing
Window lifters (or, to use a more familiar word, “window lifters”), as the name suggests, are designed to raise/lower windows.
The option under consideration refers to the electric window lifter
(although in a number of models only mechanical ones are provided for rear windows), i.e. manipulations with the side windows are carried out using electrical energy.
It is convenient and practical, creating additional comfort for the driver and passengers. It is pleasant to note that domestic manufacturers have paid due attention to this indicator.
Installation of rear ESP
The need to replace the ESP may arise for a number of reasons. The most common ones are:
- the corresponding fuse has blown;
- poor-quality connection of wires and, as a result, lack of contact;
- failure of the electric motor.
In any of the above cases, replacement (or repair) of the mechanism is necessary. Let’s make a reservation right away - for most amateurs, self-repair is a difficult task, so it will not be considered here. We will simply describe the process of removing the mechanism - accordingly, installation is carried out in the reverse order.
At the first stage
We get access to the ESP. To do this, you need to remove the decorative edge. The process is quite simple and does not require additional description. Let us remind you that the windows must be pre-fixed in the “closed” position.
Next stage:
unscrewing the mounting bolts. We use a 10mm socket. Then we turn out the elements with which the ESP is attached to the door. Here you will have to deal with three bolts (we use an “8” head). Armed again with a “10” socket, we unscrew the nuts securing the ESP guide.
This completes the dismantling. As already mentioned, installation is done in reverse order.
As you can see, installing rear window regulators on a Priora is not difficult: you just need to unscrew the corresponding bolts. Please remember that this process requires care.
, proportionate application of force - to avoid the danger of the heads falling off. As for the unit being replaced, specialists will have to deal with it.

VAZ 2170 | Power windows
Power windows
The operating mode of the power windows is determined not only by the switches, but also by the power window control unit on the support with additional relays on the left under the dashboard.
Operation: When the ignition is on, the window in the driver's or passenger's door next to the driver slides up or down until it stops by briefly pressing or releasing the switch. In this case, the movement of the glass stops if you briefly press the key in the opposite direction.
For safety reasons, this convenient method of activation in the rear doors only exists for lowering the windows.
When the ignition is turned off, when you press the button, all windows move all the way down only. The glass only moves up when the power window button is pressed.
Child protection: The electric windows in the rear doors are locked by a central switch in the driver's door armrest.
Anti-theft device: If the driver's door is opened and closed again while the engine is off, all power windows are disabled.
Convenient closing: In all vehicles with power windows, they can be closed simultaneously when the driver's door and the passenger door next to the driver are closed. To do this, you need to hold the key in the “closed” position a little longer. If there is an electric sliding roof, it also closes at the same time.
Protection against jamming: If the glass encounters an obstacle when lifting upward, it immediately begins to move in the opposite direction and drops a few centimeters.

Table of measuring values for window regulators
The table shows the nominal values using the driver's door window regulator as an example (vehicles with four power windows).
On rear windows and in cars with two power windows, wires of different colors are partially laid (see footnotes).
The control panel is located on the interior handle
The window regulator on the Priora is used to raise or lower the windows in the car. The mechanism is installed inside the car doors either in a special subframe or by attaching it to the car body.
The design of the window regulator includes:
- drive (combined electric motor unit, worm, gear);
- window lifting mechanism;
- Control block.
