Rear Window Wiper
The rear window wiper system consists of a rear wiper relay and an integrated wiper motor and module assembly, which contains internal washer and wiper relays.
When the multifunction switch is set to the rear wiper intermittent position(s), it supplies ground to the rear window wiper motor module inputs and the wiper motor operates in intermittent mode. During intermittent operation, the rear wiper motor momentarily activates the rear window wiper relay (internal) which sends voltage to the motor. Once the rear window wiper motor is activated, the internal run/park switch connects voltage to the motor, keeping it operating. When the rear window wiper motor returns to the PARK position, the run/park switch disconnects voltage internally from the wiper motor input, reconnecting it to the rear window wiper motor module output. The rear window wiper remains parked until the rear window wiper motor module completes a time-out and then repeats the cycle.
