Test H: The Washer Pump is Inoperative

PINPOINT TEST H: THE WASHER PUMP IS INOPERATIVE

Normal Operation
Under normal operation, the multi-function switch provides input to the windshield wiper motor through circuit CRW07 (GY/BN) to activate the windshield washer. The windshield wiper motor activates the internal relay and then provides power to the washer pump through circuit CRW14 (BU/WH). The washer pump is grounded through circuit GD120 (BK/GN).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Multi-function switch
- Washer pump motor
- Windshield wiper motor
