Test F: The Wash and Wipe Function Is Inoperative

PINPOINT TEST F: THE WASH AND WIPE FUNCTION IS INOPERATIVE


F1-F3:






Normal Operation
The mist function is activated when the module (internal) receives a reference signal through circuit 680 (LB/OG). When the wash button is pressed for longer than 0.25 second, the windshield wiper motor cycles, sending battery voltage through circuit 941 (BK/WH) to the washer pump motor.

Possible Causes
- Circuit 680 (LB/OG) open
- Windshield wiper/washer switch
- Windshield wiper motor
