DESCRIPTION OF OPERATION
Windscreen Wipers
The car's windscreen wipers can run at two speeds and intermittently. The system also includes windscreen washers.

Current is supplied via fuse 8 to windscreen wiper switch 61, wiper motor terminal 53A, and to relay 83 for intermittent operation.

With switch 61 in position J (intermittent operation), current is supplied from terminal J to the intermittent operation relay, causing it to operate.

The relay contacts close and current flows from terminal 53M to switch terminal 31b, through the switch and on to wiper motor terminal 53. The wiper motor now operates the wipers at regular intervals. The intermittent operation relay controls the time between wipes.

With the switch in position I, current flows from terminal 53 to wiper motor terminal 53 and the motor runs at low speed. This is the same as for position T, but in this position the switch is spring-loaded.

With the switch in position II, current flows from terminal 53b to wiper motor terminal 53b. The motor now runs at high speed.

The wiper motor has an integral mechanically controlled switch. This controls the current so that the wiper motor always returns to the parked position after the current has been cut off with the switch.

This is achieved by the windscreen wiper motor being supplied with current from terminal 53a via the integral rest position switch. The current flows via the rest position switch through the intermittent operation relay and switch and then back to the windscreen wiper motor.

In the wiper's rest position, this contact is broken and as terminals 53 and 53b are then without current, the motor stops.

Washing starts when the stalk switch is moved towards the steering wheel rim (position P). Washer motor 63 is then supplied with current from terminal P of the switch.

If the stalk switch is only moved momentarily towards the steering wheel rim, the wipers automatically wipe four times.

FAULT DIAGNOSIS HINTS
Windscreen Wipers
1. Check that fuse 5 is intact and supplied with current.
2. Check the connectors, wiring harness and ground connections.
