Washer Operation

When the washer switch is pushed, battery voltage is applied to the wiper motor through the wiper speed signal circuit, CKT 478. The wiper motor has voltage applied to it automatically by the wiper motor cover circuit board and operates at low speed during the wash cycle and then for two sweeps after the wash cycle is complete. If the wipers had been in DELAY, LO, or HI, they would return to that operation after the wash cycle.
