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.
Windshield Washer
When the washer switch is pulled towards the driver, the SASM sends the washer request to the BCM over the LIN. The BCM activates the windshield wash relay (internal to the BCM) and sends a message to the driver side windshield wiper motor. When the BCM activates the windshield wash relay, voltage is provided to the washer pump, directing washer fluid to the windshield. When the switch is released, the windshield wiper motor continues to activate the windshield wipers for 3 additional wipes and then turns the windshield wipers off.
Heated Windshield Washer Jets
If equipped, the heated windshield washer jets are designed to keep the washer fluid from freezing within the washer nozzles when sub-freezing temperatures are present. The heated windshield washer jets are provided voltage when the ignition is on.
