Window regulators with the electric drive
The mode of functioning of window regulators decides not only by switches, but also the control unit of window regulators on a support on additional relays under the control panel at the left.
Functioning: at the included ignition glass at doors of the driver or passenger near the driver slides up or down to an emphasis by short pressing or a switch otzhatiya. At the same time the movement of glass stops if shortly to press a key in an opposite direction.
For safety reasons such comfortable way of inclusion in back doors exists only for glass descent.
At the switched-off ignition when pressing the button all glasses move against the stop only down. Glass moves up only if the window regulator key is pressed.
Protection of children: window regulators with the electric drive in back doors are blocked by the central switch in an armrest of a door of the driver.
Anti-theft device: if at the switched-off engine the door of the driver opens and is again closed, all window regulators are disconnected.
Comfortable closing: in all cars where there are window regulators with the electric drive, they can be closed at the same time when closing a door of the driver and the passenger's door near the driver. For this purpose it is slightly longer necessary to take a key in situation "is closed". In the presence of a sliding roof with the electric drive it too at the same time is closed.
Protection when jamming: If at rise up glass encounters an obstacle, then it begins the movement in the opposite direction at once and falls by several centimeters.
Malfunctions
|
|
- If any glass does not move, check automatic switches in nests 22 and 23 in "a 8-seater support of the relay" under the control panel for conductivity at the left.
- Check of switches: If only one window regulator does not work, then try to put it in action from the second switch.
- Thus you will be able to establish whether there is no malfunction source in the first switch.
- Such inspection cannot be carried out with glass at the driver's doors. Remove facing of a door.
- For the sake of experience trade places sockets of switches so that glass at doors of the driver was put in action by definitely serviceable switch.
- Check of the bringing wire: if the switch as it should be, then disconnect the wire socket in the engine of a window regulator and check the voltmeter the socket whether on a window regulator the correct signals really arrive.
- If tension indicators correct, then the engine of window regulators remains a source of defect.
- But if on the engine tension does not move, then check a wire and the control unit.
- The bad movement of glass can be a consequence of the jammed window guide.

Table of measuring sizes of window regulators
Nominal sizes on the example of a window regulator of a door of the driver are specified in the table (cars with four window regulators).
On back glasses and in cars with two window regulators wires of other flowers are partially laid (see footnotes).

Temporary help on the way
For window regulators with the electric drive any mechanical emergency control is not provided. But if window regulators do not work, then you do not need to go with an open window:
|
|
- If the switch is faulty, then try to close a window by means of the second switch.
- If it did not turn out (for example, at the driver's doors), then dismantle the switch of other window or connect a connecting wire to the second, serviceable switch (about dismantle of switches in this chapter above).
- By means of this serviceable switch you will be able to close a window.
- If the engine of a window regulator is faulty, then it can be dismantled, having removed facing of a door. For this purpose weaken tightening connection between a window and a window regulator (screws on a reverse side – the head Detali of a body).
- Now shift glass up and record in this situation with the help of an adhesive tape or a wooden wedge.

Replacement of the engine of a window regulator
Engines of window regulators are dismantled the same as mechanical elevators (the head Detali of a body). In installation of the engine of a window regulator programming of an emphasis is important:
|
|
- Include ignition.
- By means of the switch lift glass up to an emphasis.
- Now several times within a second take the switch in situation "top".
- Check: press the switch in a position "down". Now glass has to fall down to an emphasis.
- Repair of the electric motor is not provided.
