Operation
All window regulators in the car can be operated by means of switches in the centre console between the front seats. Under certain circumstances, the window regulator in each of the rear doors can also be operated by means of switches in the corresponding door.

The supply is taken from fuse 11, via the 29-pole white connector 152A, to the following switches on the centre console:

Switch 189, for switching in and out the window regulators in the rear doors

Switches 162 (driver's door), 163 (co-driver's door), 190 (left-hand rear door) and 191 (right- hand rear door)

If switch 189 is closed, the rear window regulators can also be operated from switches 190A in the left- hand rear door and 19IA in the right-hand rear door.

If switch 189 is open, the switches in the rear doors will be inoperative. The window regulators in the rear doors can then only be operated by means of the switches on the centre console.

As an example, if switch 190 (for the left-hand rear door) on the centre console is depressed, one of the two pairs of contact (depending on whether the window is to be raised or lowered) will close. Current will then flow to switch 190A in the left-hand rear door, through the switch and to regulator motor 193. It then flows through the second pair of contacts of the switch, back to the switch on the centre console and to earth (65).

For information on the switch lighting, see the section entitled Lighting for switches and controls. Note: The wiring varies for the various markets and model years.

Automatic window regulator controls
Unlike the other switches, driver's door switch 162 has two positions for lowering the window. This switch is also connected to time-delay relay 287.

Position 1: The window travels downwards as long as the switch is kept depressed in this position. A positive voltage is supplied to motor 164 across pin 2 on the switch and across the relay contacts. The motor will stop when the switch is released.

Position 2: The window opens fully even if the switch is released after a brief instant.

The coil of relay 287 is now supplied with a positive voltage across pin 5 of the switch and the relay is energized. The motor is supplied across the closed relay contacts (pin 15). The supply is maintained (for approx. 6 seconds) by the time-delay function of the relay until the window has been lowered fully, even if the switch is released immediately. (The downward travel of the window may be interrupted by setting the switch to position 3, "Raise".)

Position 3: The window will travel upwards as long as the switch is held depressed in this position. The motor is supplied across pin 7 on the switch and the direction of rotation is reversed, causing the window to be raised.

Fault-tracing hints
The electric window regulators will be operative when the ignition switch is in the drive position.

1. Check fuse 11 and check that the supply to it is live.

2. Check that terminal 7 of switch 189 and terminals 3 and 6 of the other switches in the centre console are live. (On 162, terminal 3 only.)

If the window regulators in the rear doors cannot be operated from the corresponding switches in the rear doors, check that current flows from switch 189 to terminals 3 and 6 of these switches as well.

3. Check the switches by measuring at their terminals.

4. Check the connectors, cable harnesses and earth connections.

Automatic window regulator controls
Check the automatic window regulator controls as follows: Set switch 162 to position 2 and check that the supply to pin 4 on the relay is live. Pin 1 should be earthed.

Check that pin 3 and pin 15 on the relay are live.
