Wash/wipe

Wash/wipe

When the wash switch is operated, battery voltage on an LGO wire is switched from fuse B8 in the passenger compartment fuse box on an OR wire to one terminal of the washer pump. Since the other washer pump terminal is permanently connected to earth on a B wire, the pump will dispense water to the screen. Simultaneously the front wiper control unit receives battery voltage on an OR wire. The front wiper control unit responds by supplying battery voltage on an NLG wire via the wash/wipe low switch to the wiper motor slow speed terminal on a ULG wire. Since the other motor terminal is permanently connected to earth on a B wire, the motor will rotate causing the wiper blades to operate.

Wiper motor park The integral wiper motor park switch is designed to switch battery voltage from fuse B8 in the passenger compartment fuse box on an LGO wire to the front wiper control unit on an NLG wire. This ensures that, when the wash/wipe switch is turned to the OFF position, the wiper control unit responds by supplying battery voltage on an NLG wire via the wash/wipe low switch to the wiper motor slow speed terminal on a ULG wire. This returns the park switch to the rest position.
