Technical characteristics

window raiser with the electric drive

The functioning mode Glass lifts is defined not only switches, but also the management block window lifterами on a support with additional relays at the left under a control panel.

Functioning: at the included ignition glass at doors of the driver or the passenger near to the driver slides upwards or down to an emphasis by short pressing or отжатия the switch. Thus glass movement stops if shortly to press a key in an opposite direction.

From reasons of safety such comfortable way of inclusion in back doors exists only for glass descent.

At the switched off ignition by pressing the button all glasses move against the stop only downwards. Glass moves upwards only in the event that the key window lifterа is pressed.

Protection of children: window raiser with the electric drive in back doors are blocked by the central switch in an armrest of a door of the driver.

The antijoy ride device: if at the switched off engine the door of the driver opens and is again closed, all window raiser are disconnected.

Comfortable closing: in all cars where is window raiser with the electric drive, they can be closed simultaneously at closing of a door of the driver and a door of the passenger near to the driver. For this purpose it is necessary hardly to take longer a key in position "is closed". In the presence of a sliding roof with the electric drive it too is thus closed.

Protection at jamming: If at lifting upwards glass encounters an obstacle it begins at once movement in the opposite direction and falls on some centimetres.



  1. If any glass does not move, check up automatic switches in nests 22 and 23 in a 8-seater support of the relay at the left under a control panel on conductivity.
  2. Check of switches: If one does not work only window lifter try to put it in action from the second switch.
  3. Thus you can establish, whether there is a malfunction source in the first switch.
  4. Such check cannot be spent with glass to doors of the driver. Remove door facing.
  5. For the sake of experience change in places sockets of switches so that glass at doors of the driver was put in action by definitely serviceable switch.
  6. Check of a bringing wire: if the switch is perfectly in order, disconnect a wire socket in the engine window lifterа and check up the voltmeter a socket, whether really arrive on window lifter correct signals.
  7. If pressure indicators correct a defect source there is an engine Glass lifts.
  8. But if on the engine pressure does not move, check up a wire and the management block.
  9. Bad movement of glass can be a consequence jammed directing windows.

The table of measuring sizes Glass lifts

In the table nominal sizes on an example window lifterа doors of the driver (cars with four window lifterами) are resulted.

On back glasses and in cars with two window lifterами wires of other colours (footnotes see) are partially laid.

The time help on the journey

For Glass lifts with the electric drive any mechanical emergency control is not provided. But if window raiser do not work, you do not need to go with an open window:


  1. If the switch is faulty, try to close a window by means of the second switch.
  2. If it has not turned out (for example, at doors of the driver) dismantle the switch of other window or connect a connecting wire to the second, serviceable switch (about dismantle of switches in this chapter above).
  3. By means of this serviceable switch you can close a window.
  4. If the engine window lifterа is faulty, it can be dismantled, having removed door facing. For this purpose ослабьте tightening connection between a window and window lifterом (screws on an underside – the head of the Detail of a body).
  5. Now shift glass upwards and fix in this position by means of a sticky tape or a wooden wedge.

Replacement of the engine of the glass-lift

Engines Glass lifts are dismantled the same as mechanical lifts (the head of the Detail of a body). In engine installation window lifterа programming of an emphasis is important:


  1. Include ignition.
  2. By means of the switch lift glass upwards against the stop.
  3. Now some times within a second take the switch in position "top".
  4. Check: press the switch in a position "downwards". Now glass should fall itself down to an emphasis.
  5. Electric motor repair is not provided.
