Washer Operation

When the washer switch is pushed, battery voltage is applied to the circuit board through the PNK and GRY wires. The park switch coil is energized by the battery voltage at terminal B of connector C1. The circuit board turns on the washer pump and the wiper motor by closing contacts A and B. The circuit board turns the wiper motor off approximately six seconds after it interrupts power to the washer pump. If the wipers had been in DELAY, LO, or HI, they would return to that operation after the wash cycle.
