Rear Wiper/Washer System
CIRCUIT OPERATIONRear Wiper
Voltage is applied at all times through the PWR ACC Circuit Breaker to terminal A of the Rear Wiper Module. When the Rear 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 Wiper/Washer Control Switch and the Tailgate Lock Switch to terminal C of the Rear Wiper Module. Voltage is then applied to the Rear Wiper Motor and the Motor operates. The Rear Wiper Module is grounded through Terminal B to ground G411. When the Rear 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.
Rear Washer
When the Rear Wiper/Washer Control Switch is in WASH, voltage is applied through the WDO Circuit Breaker and the Rear Wiper/Washer Control Switch to the Rear Washer Pump. The Pump operates as long as the Control Switch is held in WASH.
