What is the reason for the failure of all the Lavida power windows?

It may be that the window button is not sensitive, or there is a problem with the wiring, check the wiring of the cab lift switch, and if there is no problem with the wiring, the switch needs to be replaced. If you can't control it with a car key, it may be that the car window lifter is malfunctioning.

The failure of the 4 main driver's window controllers may be that the window button of the main driver's seat is not sensitive, or there is a problem with the line, check the circuit of the cab lift switch, if there is no problem with the line, the switch needs to be replaced. If you can't control it with a car key, it may be that the car window lifter is malfunctioning.

Modern automobiles are demanding more and more comfort and convenience from windows, and power windows have increasingly become a common feature in automobiles. The so-called power window is a device that drives the glass regulator motor through the on-board power supply, makes the lifter move up and down, and drives the window glass to move up and down, so as to achieve the purpose of automatic opening and closing of the window. The power window can make the driver or occupant sit in the seat, and the door glass can be automatically raised and lowered by using the switch, which is easy to operate and conducive to driving safety, and has become the first choice in the window design of various OEMs.

The power window system consists of a window, a window regulator, an electric motor, a relay, a switch, and an ECU. Among them, the glass regulator system is the main component of the power window, according to the different working principles of the mechanical lifting mechanism, the glass regulator can be divided into 3 forms: rope wheel type, wishbone type and flexible shaft type.

The car power window system is composed of windows, window regulators, motors, relays, switches and other devices. This is also one of the most commonly used configurations for car owners, which is simple to operate and greatly convenient for car owners. However, with the growth of vehicle use time, the car power window will also be unable to lift the situation, let's take a look at the reasons and solutions for the power window can not be lifted.

1. The window lifting motor is damaged or the contact of the electronic control wiring harness is poor.

If there is a burnt smell or an abnormal sound in the door panel when you press and hold the window opening button, it is likely that the window lift motor parts are damaged, and it is recommended to directly find a 4S shop or auto repair shop to replace the glass lift motor.

2. Motor overheating protection.

In order to protect the power supply circuit, the general window lift motor is equipped with an overheating protection mechanism, if the components overheat for some reason, the motor will enter the overheat protection state, resulting in the failure of the window lifting. In this case, just wait for the motor to cool down.

3. The guide rail is blocked or the rubber strip is aging.

Most of the window glass can not be lifted is caused by the stagnation of the body, we only need to clean the guide rail and apply some lubricating oil, if it is the failure caused by the aging and deformation of the glass strip, you need to replace the new sealing strip, if it is dirty, clean it directly. Spraying a glass seal with sheet wax or applying talcum powder (lubrication) usually works well.

4. Initialization data loss.

When the battery is powered off or other systems are repaired, the power supply or ground wire of the window control module is disconnected, so that the initialization data of the window is lost, and the window cannot be raised or lowered. In this case, the window should be reset, the method is: turn on the ignition switch, pull the switch up and save, continue to pull the glass for more than 3 seconds after it rises to the top, release the switch and immediately press and hold, so that the glass falls to the bottom and wait for more than 3 seconds, and repeat the rising action again.

5. The glass regulator switch is damaged.

The window lifter switch of the car is a very frequently used switch on the car, and it is used almost as long as you drive, so the probability of damage is also very high. At this time, we only need to directly replace the entire glass regulator switch in the store, if you are interested in replacing it directly, you can buy it yourself, the cost is dozens of yuan, and the tutorial can be queried on the Internet, which is not difficult.

Hope! Thank you.

The reason for the failure of all Lavida power windows is: when the window glass is continuously lifted and lowered several times, in order to prevent the glass lifting motor from overheating and causing damage, the window window lifting function may be temporarily closed for a few seconds, and you can wait for the function to be restored before operating; The lifter has been damaged and needs to be replaced; The door control module is abnormal, and the window regulator control button is out of order; The battery is running out of power. Taking the 2021 Lavida Manual Fashion Edition as an example, it is a compact 4-door 5-seater sedan owned by SAIC Volkswagen, with a length, width and height of 4670mm, 1806mm, and 1474mm respectively, with a wheelbase of 2688mm, and it is equipped with a 5-speed manual gearbox with a top speed of 190 kilometers per hour.

Volkswagen Lavida glass one-key lifting failure, window glass can not be lifted and similar problems. It doesn't have to be a serious mechanical failure. You can try to check and deal with it yourself. Some may be minor problems, and there is no need to go directly to the 4S store to waste money.

Glass regulator is a lifting device for automobile door and window glass, which is mainly divided into two categories: electric glass regulator and manual glass regulator. At present, many automobile doors and windows have given up the crank-type manual lifting mode, and the push-button electric lifting mode is generally adopted. Lavida's glass lifting method is electric button type.

Reasons and solutions for the inability of electric windows to be lifted:

1.The window lift motor is damaged or the electrical control harness is in poor contact.

When the window opening button is pressed for a long time, if the door panel has a burning smell or abnormal noise, it is likely that the window lift motor parts are damaged. In this case, it is recommended to go directly to a 4S shop or auto repair shop to replace the glass lifting motor.

2.Motor overheating protection.

In order to protect the power supply circuit, the general window lift motor is equipped with an overheat protection mechanism. If the component overheats for any reason, the motor will enter an overheating protection state, resulting in failure to raise and lower the window. When this happens, just wait for the motor to cool down.

3.Blocked rails or aging tape.

Most of the reason why the windows can't be lifted is the stagnation of the body. All I need to do is clean the rails and apply some lube. If the failure is caused by the aging and deformation of the glass strip, we need to replace the sealing strip with a new one.

If it's too dirty, wash it directly. Spraying some surface wax on the glass seal, or applying talcum powder (for lubrication), usually works well.

4.Initialization data loss.

When the battery is powered off or other system repairs, the power supply of the window control module or the stool friend ground wire is disconnected, resulting in the loss of window initialization data and the window cannot be lifted. When this happens, re-set the window lifting. Method:

Turn on the ignition switch, pull the switch up and hold, continue to pull for more than 3 seconds after the glass rises to the top, release the switch, press and hold it immediately, let the glass go down to the bottom for more than 3 seconds, and repeat the rising action again.

5.The glass regulator switch is damaged.

Window lifter switches are very frequently used switches in cars, almost as long as you drive, so the probability of damage is also high. At this time, we only need to directly replace the switch of the entire window regulator in the store. If you are interested in replacing it directly, you can buy it yourself, and it costs dozens of dollars.

The cause of the failure of all window lifting capacity may be the disconnection of the grounding wire of the combination switch, the fracture of the total power supply, the poor contact of the window relay contact, the damage of the resistance or the damage of the coil, the poor contact or failure of the safety switch, etc., which may be caused by insufficient power and need to be reset. Press the switch to the top and hold the switch for more than 3 seconds, and then put the glass to the bottom and hold it for 3 seconds.

It is recommended to go to the 4S shop for inspection and maintenance to determine the specific problem.

Glass regulator is a lifting device for automobile door and window glass, which is mainly divided into two categories: electric glass regulator and manual glass regulator. At present, the lifting (closing and opening) of many car door and window glass has abandoned the manual lifting method of the crank type, and generally changes to the electric lifting method of the button type, and the glass lifting method on Lavida is the electric button type.

The reason why the windows of Volkswagen Lavida cannot be raised and lowered may be that the switch is not good, after the window is raised to the top, then pull the button up for about 2 seconds, and then lower the glass to the low button and press down for about 2 seconds. After powering on (you can not start) press the close button to turn off, and then continue to press for a few seconds to resume.

The glass does not lift, generally it may be that the glass regulator switch is broken, followed by the glass lifting mechanism, it is also possible that the cable plug in the combination switch is loose, there are material quality problems, and there are also days of thermal deformation, resulting in poor contact.

The root cause of this fault is poor contact, and as long as it is solved, it should be able to eliminate the fault.

The way to solve it, :

1. One is to clean the black contacts of the middle layer of rubber pads, and use eraser, alcohol or other detergents.

2. The other is to clamp the pins of the two wires in the circuit.

The activity of the power window is controlled by the main switch in the main power window switch, when the main switch is in the off position, only the window of the driver's door can be opened or closed, when the main switch is in the ON position, all the windows can be opened or closed by the main power window switch or the window switch in the door, the driver's window switch has an automatic descending mode, as long as the switch button is pressed to the second grid position, it can be started.

The power windows are pulled by reversible motors, each protected by a built-in circuit breaker that disconnects the circuit if the window switch is left open for too long (the window is obstructed or after the upper and lower limits), and then automatically resets when it cools.

When the ignition switch is in the RUN or START position, or after 10 minutes in the OFF position, the integrated controller supplies the coil voltage to the power window relay, and the relay contacts are closed, and the voltage goes to the main power window switch and the window switch in the door.

The window next to the driver.

When the ignition switch is in the RUN or START position, or 10 minutes after the OFF position, the integrated controller will turn on the power window relay voltage, the relay contact is closed, and the voltage leads to the electric window switch next to the driver. When the voltage is set to the down position, the direction of the voltage is reversed, and when you hold down and do not let go, the motor moves the window down.

Automatic descent (driver's window).

When the ignition switch is in the RUN or START position, the voltage leads to the electric window relay coil through the integrated controller, the electric window relay contact is closed, the voltage leads to the driver's electric window switch when the driver's side switch is adjusted to the auto down position, the voltage is connected to the electric window motor through the driver's window switch, when the motor is running, the controller will receive the pulse from the pulse input signal, when the window is completely lowered, the motor stops, the pulse signal no longer occurs in the pulse, and the controller at the input end of the pulse is sensed to the rear, the voltage is no longer sent to the power window motor.

10 minutes after the passenger window ignition switch is turned to the off position in the run, the voltage is transferred by the integrated controller to the power window relay coil, the power window relay contact is closed, and the voltage is supplied to all window switches, when the main instrument panel master switch is opened, the passenger window can be controlled by the door switch or the main instrument panel.

When the right front door and window switch is adjusted to up, the voltage leads to the right front electric window motor, and the motor realizes the tie iron through the right front electric window switch and the main instrument panel switch contact, and the window has been rising until the up position is released, if the right front door and window switch is adjusted to the down position, the voltage will go to the opposite direction; The window is moved down until it is released, and the other windows behave similarly.

It may be a problem with the switch, and there is another possibility that the line is short-circuited by moisture, causing the window to be sent all the time. My car has this situation after cleaning the air conditioner, the line is damp when cleaning the air conditioner, and your situation is the same, the passenger side of the door will automatically lower the window as soon as the power is on, and then the air conditioner is turned on and blows hard, that is, the moisture is blown away, and it will be good for 5 minutes to blow.
