DESCRIPTION OF OPERATION
Only the CS model is equipped 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 62R.
When switch 61 a 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 elapsing 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. Current flows via the rest-position switch through the intermittent operation relay and then back to the rear window wiper motor.
In the wiper rest position, this contact is broken and if terminal 53B is then without current the motor will stop. Washing starts when the button (spring-loaded) 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 wiper motor 63 is supplied with current from relay terminal 87.
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 washer is in operation.

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.
3. Check that the terminals in the above image are supplied with current in the different switch positions.
