DESCRIPTION OF OPERATION
When the ignition switch is in the Drive position, current is supplied:
^ via fuse 31 to stalk switch 61 which controls the headlamp washers and wipers.
^ via fuse 10 to each headlamp wiper motor 66.

When the stalk is moved towards the steering wheel rim, the contacts in the switch close. Headlamp wiper motors 66 and washer motor 63 start simultaneously.

When the stalk is released, breaking the circuit, the wiper motors continue to be supplied with current (via fuse 10).

When the wiper motors have completed a cycle of 2 strokes, their limit switches open the circuit and the wipers stop in the parked position.

A diode in each motor prevents current from the motor's feedback circuit from flowing back to the washer motor.

Each wiper motor incorporates overload protection in the form of a cut-out actuated by a resistor. The cutout is connected in series with the motor and trips if the load is excessive (if the wiper blades have frozen to the headlamp lenses, for instance).

FAULT DIAGNOSIS HINTS
The headlamp wipers and washer motor can only be started when the ignition switch is in the Drive position.
1. Check that fuses 31 and 10 are intact and supplied with current.
2. Check that current is present on pin 6 of the stalk switch and on the connections of the wiper motors.
3. Move the stalk switch towards the steering wheel rim and check that current is supplied to the wiper motors and the washer motor.
4. Check the connectors, wiring harness and ground connections.
