Front Door Window Regulator: Description and Operation

Electrical Comfort Window Regulator (Automatic Run-up And Run-down) With Pinch Protection

With introduction of the comfort window regulator, the front window regulators are equipped in addition with automatic run-up and run-down functions.

Switch for automatic run-up and run-down for front windows are located in drivers door operating unit. Switches for driver and passenger door are equipped with a two-step function.

If the respective switch is pushed or pulled to the first step, the front window is opened or closed ("manually") as long as the switch is held or the respective end position is reached.

When the switch is pressed or pulled completely to the second step, the front window automatically opens or closes completely.

Additionally, the front passengers door has a switch to operate the front passengers side window without two-step function.

All electrical window regulators are equipped with pinch protection. Window closing is automatically interrupted if obstructions block the closing route.

However, this does not apply when closing the windows from outside using the ignition key - in this case there is no pinch protection.

In this case the window can only be closed again when the ignition is switched on.

For vehicles with central locking system, the windows can be closed and opened also from outside. To do so, the key must only be held in the closing/opening position.

Establishing automatic run-up and run-down

NOTE: After disconnecting and connecting the vehicle battery, the automatic run-up and rundown of drivers and passengers door is without function.

In order to restore this function after connecting the battery, proceed as follows:
- Lock vehicle from outside using drivers or front passengers door.

When doing this, make sure that all doors and windows are completely closed.

- Unlock vehicle and lock again via the drivers or passengers door. While doing this, hold the key in lock position for at least one second.

The automatic run-up and run-down of the drivers and passengers window is reactivated.

If there is a malfunction of the electrical window regulators, this is indicated by blinking of switch lights in drivers and passengers door.

All lights in the door trim will flash for approx. 15 seconds after switching on the ignition.
