Modern window regulators are part of the car's electronics. Manual devices have long been a thing of the past; today, electric designs are used. Despite their convenience and practicality, they are considered less reliable than mechanical ones, which means they fail more often.
Any owner of a Lada Priora may sooner or later notice that the window regulator on his car does not work. Front and rear devices have approximately equal chances of failure. However, if your window regulator stops working, the problem must be corrected, because otherwise you will not be able to open or close the window. Some problems can be solved on your own, and in some cases you will have to contact a service center. Today we’ll talk about why the window regulator on the Lada Priora does not work and how to solve the problem.
Possible breakdowns
The window regulator on the Priora does not work and this is due to a number of reasons, the essence of which we will look into in detail. So, a passenger car VAZ-2170 Priora can be equipped by the manufacturer with electric windows for:
- Two front doors
. As a rule, the two rear doors are equipped with manual rack-and-pinion lifts (window lifters are installed separately on them); - On all four doors.
Depending on the type, devices of the cable and rack operating principle are distinguished. By type, there are faults associated with the electrical and mechanical parts.
The most common mechanical failures include:
- “Licking” of teeth on the gear of the lifting mechanism;
- Defects in the cable mechanism that led to its damage or excessive stretching, which subsequently causes it to jump off the guide rollers.
As we see, there are few mechanical reasons and they are extremely rare.
Electrical defects
If it happens that all four window regulators fail, then the reason must initially be sought in fuse number F31
, which is located in the central power supply control unit. The manufacturer placed the fuse and relay mounting block under the steering rack. So getting there and checking the condition will not be difficult for any driver, even an inexperienced one.
You just need to open the plastic panel under the steering wheel and perform a visual inspection to find the damaged (burnt out) mechanism.
If you have problems opening the rear doors using the control buttons that are located on the door compartments, but the windows are driven by the central control unit, then we begin to look for the reason in a mechanism called the rear window switch. Often the mechanism randomly blocks the current supply, as a result of which the glass does not move.
Diagnostics are carried out
using a tester. If the product does not pass current, then it should be replaced with a working one, since it cannot be repaired. The cost of the device is low, so there will be no big expenses.
Next breakdown option
when one window regulator is faulty and cannot be moved using the central control unit. First of all, we test the mechanism on the corresponding doorway. If there are no complaints about the operation of the relay button, then we look for the cause in the head power supply, otherwise we replace the faulty relay. We finally check the entire system for serviceability.
In addition, a possible breakdown could be trivial mechanical damage to the electrical wire, as people say, it has become frayed. It can be eliminated by twisting or soldering the two ends of the wire, followed by mandatory insulation for safety purposes.
Now, as for the electric motor itself, the cause of the breakdown may be, and, as a rule, it is, significant wear of the commutator brushes
(freezing). Such freezing occurs due to the fact that the part is structurally made of plastic and, due to heating, can be deformed and modified.
The brush becomes motionless or inactive and is not able to perform its functions in full. Another reason why the power window on the Priora does not work. As you can see, you can eliminate the cause of the breakdown yourself, without having the proper experience, everything is quite simple and clear.
Resynchronization of remote control codes
The ECU transmits data to the Lada Priora remote control via a radio channel and a transponder channel. Problems arise with the radio channel: if you press buttons (send a car signal) outside its coverage area, then after 1000 presses the code is resynchronized: while sending a command in the radio signal area, the electrical package will not perceive the remote control code.
Also, a code error may occur if the battery is discharged: in this case, the ECU will briefly generate a random code that will erase the codes of all remote control chips. In these cases, you will have to enter the remote control data into the electronic control unit again.
A flip key for Lada Priora is, first of all, beautiful. It is pleasant to the touch; all remote control buttons are located on the body. Its undeniable advantage is that it will not damage the fabric during storage, because its blade will be hidden. The blade is attached to it more securely, and it will not loosen the remote control chip.
I read a lot, but didn't find it. My standard immobilizer was disabled. Yesterday I tried in every possible way to start the car with both the red and black keys, in the end I started the car, but now the buttons on the thrown black key do not work, but the car starts with it. I tried to retrain it, but to no avail, from inside the door windows work with the buttons on the door. I pulled out the board, it doesn’t respond, the battery is new
Why does the Priora window lifter not work?
Window lifter failure may occur due to a malfunction of the following systems:
The window lift motor has its own wear life; if it is exceeded, the mechanism fails, and the motor itself must be replaced.
If everything is fine with the motor, but the lifts still do not work, then the cause of the breakdown may be an electrical circuit or damaged wires.
"Priors" window lifter block
The car's safety unit contains a component responsible for the car's window regulators. If it fails, the mechanism stops functioning.
The Priora window control buttons can also cause a malfunction. This mainly occurs due to oxidation of the button contacts.
Situations also arise when the functioning of the Priora windows is quite unstable. For example, they can only work when the ignition is on or they work partially. It may be that the front ones function normally, but the rear windows on the Priora do not work. Then, most likely, the problem lies in the car's electronics.
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. This is where we end
Good luck!
We end here. Good luck!
Causes of failure
Priora window lifts break down due to the car being in conditions of regular low temperatures for a long time, problems with the electronic control unit, failure of fuses, wear of the motor and other lift components, as well as skewed glass.
Before carrying out repairs, it is necessary to diagnose those car systems in which the cause of the breakdown of this element may be hidden. Diagnostics are best carried out using tools and devices, for example, a tester will allow you to understand whether voltage is supplied to the window lift motor.
Once the cause of the problem has been identified, repairs can begin.
Fuse box of Lada Priora under the hood:
It has 6 fuses F1,F2,F3,F4,F5,F6.
Fuse F1
supplies control point S2 of the ignition relay, fuel pump relay, ECU, spark plug injector, etc.
The ignition relay and fuel pump relay in Priora are located here:
Fuse F2 supplies test point S4
Fuse F3 supplies test point S1
Fuse F4 and F6 are two power fuses from + Generator to + Battery
Fuse F5 Electric power steering power

Troubleshooting control buttons
A fairly common malfunction is the failure of the window lift control buttons. Most often, the Priora power window buttons become oxidized, or their contacts begin to come off. To eliminate faults of this kind, you will need to clean the contacts from oxide or re-solder the buttons. When re-soldering, the contacts will fit snugly against each other, thereby ensuring uninterrupted operation of the power window.
Troubleshooting
Minor breakdowns include glass rattling, noise in the window lifter, free movement of glass under mechanical influence (for example, the glass does not rise or fall with the lifter, but the same can be done by hand). Their cause is skewed glass, failure of rollers or cables. If the glass is skewed, it must be adjusted. If the cable is broken, it must be replaced. If the cable comes off the rollers, you need to pull it back and adjust the car window regulator. The occurrence of noise is a sign that the mechanism is poorly lubricated. To eliminate the malfunction, you need to thoroughly lubricate all the power window mechanisms, as well as the glass guides. If the mechanism operates slowly, it should also be lubricated or replaced with a new one. Over time, the speed of lowering and raising the windows decreases due to wear and tear on the window lift motor.
Master class on installing door closers
- First, remove 2 nuts on the door trim near the driver.
- Then we lift the plastic clips and free the car threshold from the lining.
- Carefully remove the noise and temperature insulating materials and get to the power window connector shown in the figure. Be sure to ensure that all openings in the car, on the side of the body, are closed.
- Next, you need to disconnect the existing connector and install the connector of our new device.
This is all that needs to be done to install the power window closer on the Lada Priora. Now you don’t have to worry that when you turn off the ignition in your car, the window glass will remain down. The closer will do his job.
And that is not all! If you want to leave the car ventilated while closing it, the power window closer function can be disabled.
Malfunctions requiring repair at a car service center
The cause of window lift failure can be not only mechanical, but also electronic faults. This includes a breakdown of the car’s central electronics unit. If it fails, independent repair of this unit is impossible. A complete diagnosis and troubleshooting is required in a specialized service center.
The thing is that the CBKE has a number of multifunctional wires, which at the same time are responsible for the functioning of the central locking, turn signals, electric heated windows and mirrors. Trying to eliminate the electronic cause of a broken window lift can only make the problem worse.
Results
The Lada Priora car is reliable and unpretentious. However, the power windows of this model often fail. Perhaps the matter lies in the imperfection of the mechanism, perhaps in the harsh operating conditions of the vehicle. These include low and high temperatures, high intensity of use, problems with CBKE.
If the window regulator breaks down, you need to immediately repair it. Repair work begins with diagnostics, which is carried out using a number of instruments. If diagnostics at home is not possible, then you should contact a car service.
A number of breakdowns can be repaired yourself. Such breakdowns include mechanical malfunctions of the window regulator, for example, a broken motor or a broken cable. Often, the glass lift is unstable due to poorly lubricated surfaces. If the window lifts operate separately, then most likely the problem lies in the electronics. If such problems arise, you should contact a specialist. Self-repair of car electronic systems is impossible.
Of course, electric window lifts are superior to mechanical ones, mainly due to practicality. However, electric lifts fail much more often. For their stable operation, it is necessary to follow the recommendations of the car manufacturer and regularly carry out technical inspections of the vehicle.
Modern window regulators are part of the car's electronics. Manual devices have long been a thing of the past; today, electric designs are used. Despite their convenience and practicality, they are considered less reliable than mechanical ones, which means they fail more often.
Any owner of a Lada Priora may sooner or later notice that the window regulator on his car does not work. Front and rear devices have approximately equal chances of failure. However, if your window regulator stops working, the problem must be corrected, because otherwise you will not be able to open or close the window. Some problems can be solved on your own, and in some cases you will have to contact a service center. Today we’ll talk about why the window regulator on the Lada Priora does not work and how to solve the problem.
Why are glass closers needed?
Installing a glass closer
The power windows available on the Lada Priora are limited in their functions. They are inconvenient because they raise or lower the windows only when you hold down the security mode button. This creates some inconvenience when you turn off the ignition in a hurry, get out of the car and suddenly remember that you didn’t close the windows in the car.
Again, you need to do all the procedures in reverse order: insert the key into the ignition, press the power window buttons. Or you can completely forget that the windows are left open, and then uninvited guests can get into the car.
The ideal option is to close the windows independently when arming, as well as to operate the windows in the car when the engine is off. In such cases, a window closer of the “Master v1.10” type comes to the rescue. Its cost is only 700 rubles. It should be noted that when installing the door closer, you do not need to remove the door trim.
In addition, when using the glass lift only in the first function mode, there is no need to cut the existing wiring, and the installation procedure will only take 5 minutes.
Let's understand the scheme
Before you begin diagnosing a power window malfunction, you first need to familiarize yourself with the features of the vehicle's electrical circuit. If you can master it, there will be no special problems with making a diagnosis. To do this, you will have to find the car's owner's manual; there are separate wiring diagrams for the driver, passenger and rear doors. To diagnose a malfunction, you will need to know the location and connection of the following elements:
- Control block;
- central locking;
- turn signals;
- mirrors;
- blocks to the rear wiring harness, as well as to the speaker;
- window lift motor.
All described elements are indicated in the basic diagram. Why is all this needed? So that you do not mix up the connections and avoid confusion with the car’s electronics. Sometimes there are situations in which, for example, an inexperienced car enthusiast connects the right window regulator to the left side and vice versa.
After you understand the circuit, you can proceed directly to identifying the malfunction and fixing it, if you can do it yourself.
