DESCRIPTION OF OPERATION
Only the CS model is fitted with a rear window wiper. Current is supplied via fuse 8 to rear window wiper switch 61A, rear window washer relay 432 and to terminal 53A of rear window wiper motor 62A.

When switch 61A is in position 1, current is supplied from terminal 6 of the switch to the intermittent operation relay which then operates. The relay contacts close and current flows from terminal 53M to wiper motor terminal 53b. The wiper motor now runs at regular intervals. The intermittent operation relay controls the interval between wipes.

The wiper motor incorporates a mechanically actuated switch which controls the supply of current so that the motor always returns the wiper to the parked position after the circuit has been broken by the switch.

This is achieved by supplying the wiper motor 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 then back to the rear window wiper motor.

When the wiper is in the rest position this circuit will be broken and if terminal 53b is then without current the motor will stop.

Washing starts when the spring-loaded button marked with the washer symbol is pressed (position B). Rear window washer relay 432 is then supplied with current from terminal 4. The relay operates and washer motor 63 is supplied with current from terminal 87 of the relay.

The intermittent operation relay is also supplied with current via terminal T and the rear window wiper runs at the same time as the rear window is being washed.

FAULT DIAGNOSIS HINTS
The rear window wiper will be operative when the ignition switch is in the Drive position.
1. Check that fuse 8 is intact and supplied with current.
2. Check the connectors, wiring harness and ground connections.
