Rear Wiper/Washer System

REAR WIPER
Voltage is applied at all times through the PWR ACC Circuit Breaker to CKT 340 of the Rear Window Wiper Pump. When the Rear Window Wiper/Washer Control Switch is turned to "WIPE" or "WASH" and the ignition Switch is in "RUN," voltage is applied through the WDO Circuit Breaker, the Rear Window Wiper/Washer Control Switch, and the Rear Window Wiper/Washer Switch to CKT 391 of the Rear Window Wiper Pump. Voltage is then applied to the Rear Wiper Motor and the Motor operates. The Rear Window Wiper Pump is grounded through CKT 150 to ground G412. When the Rear Window Wiper/Washer Control Switch is turned to OFF, voltage is applied to the Wiper Motor from the Auto-Park Module to run the Wiper until the cam gear opens at park position. The Rear Window Wiper/Washer Latch Switch opens when the Liftgate is opened.

REAR WASHER
When the Rear Window Wiper/Washer Control Switch is in "WASH," voltage is applied through the WDO Circuit Breaker and the Rear Window Wiper/Washer Control Switch to the Rear Washer Pump. The Pump operates as long as the Control Switch is held in WASH.
