Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Washer System
The front and rear washer system share the same washer reservoir and washer pump. The front and rear wiper motor modules each contain an integral washer relay that supplies a ground path for the washer pump whenever they are inactive. When windshield wash is selected on the multi-function switch, the windshield wiper motor module activates its integral washer relay, which sends voltage to the washer pump to direct fluid to the windshield. When rear wash is selected on the multi-function switch, the rear wiper motor module activates its integral washer relay to send voltage to the washer pump to direct fluid to the rear window.
