Test E: The Wash And Wipe Functions Are Inoperative

PINPOINT TEST E: THE WASH AND WIPE FUNCTIONS ARE INOPERATIVE

E1:

E2-E3:

Normal Operation
The wash and wipe function is activated when the windshield wiper motor module (internal) receives a reference signal through circuit 8-KA7 (WH/VT). When the multifunction switch wash button is pressed for longer than 0.25 second, the windshield wiper motor cycles, sending battery voltage through circuit 75S-KA7 (YE/VT) to the washer pump motor. When the wash button is pressed for less than 0.25 second the windshield wiper motor cycles only once, which is considered the mist position.

Possible Causes
- circuit 8-KA7 (WH/VT) open
- circuit 31-KA19 (BK/RD) open
- multifunction switch
- washer pump relay
- washer pump motor
