Wiper Description

In the ON position, the rear window wiper/washer switch supplies voltage to the wiper motor through CKT 391 (GRY) and to the rear wiper/washer module through CKT 97 (LT BLU), since the wiper motor is grounded through the rear wiper/washer module, the wiper runs at normal speed.

When the rear window wiper/washer switch is turned to OFF, the rear window wiper/washer motor runs at normal speed until the wiper blade reaches the PARK position. Then, the park/run relay opens and signals the rear window wiper/washer to stop the wiper blade immediately. The wiper blade remains in the PARK position.

The rear window wiper motor has a circuit breaker that protects the motor when the wipers are blocked. The resulting high current opens the circuit breaker which resets upon cooling.
