Washer Operation

When the washer switch is held in the WASH position, the wiper/washer switch assembly applies battery voltage to terminal B of the wiper motor assembly causing it to begin wiper operation. The wiper/washer switch assembly also applies battery voltage to terminal A of the washer pump, through CKT 392, causing the washer pump to start spraying until the wiper/washer switch is released from the WASH position.
