Rear Window Wiper
When the wiper/washer switch is in the INT 1 or INT 2 (continuous wipe) position, the SCCM sends the request to the driver side windshield wiper motor assembly through the LIN. When the request is received, the windshield wiper motor momentarily supplies ground to the rear window wiper motor, activating the motor. The position of the wiper/washer switch determines how many times per minute the windshield wiper motor provides ground to activate the rear window wiper motor.
The rear window wiper motor is self-parking.
