Normal Operation
When the windshield washer function is selected, the wiper/washer switch provides voltage to the washer pump on circuit 33-KA34 (YE/BK). The wiper/washer switch switches circuit 32-KA34 (WH/BK) to ground through circuit 31-KA19 (BK) and the washer pump provides washer solvent to the front nozzles. When the rear window washer function is selected, if equipped, voltage is supplied through the wiper/washer switch to the washer pump through circuit 32-KA34 (WH/BK). The wiper/washer switch switches circuit 33-KA34 (YE/BK) to ground through circuit 31-KA19 (BK) and the washer pump reverses direction to provide washer solvent to the rear nozzle.
