Component Description

Rear Wiper Motor 

The rear window wiper motor contains a logic module, an integrated relay and a single speed motor. The integrated relay is used to both operate and park the motor.

Front Wiper Motor 

The logic module inside the windshield (front) wiper motor controls the rear window wiper and washer based on the inputs from the SCCM. The logic module controls the coil side of the rear window wiper motor relay and the coil side of the rear washer relay in the BJB.

Wiper/Washer Switch 

The wiper/washer switch provides the following inputs to the SCCM for the rear wiper/wash functions.

• INT 1
• INT 2
• Rear washer

Washer Pump 

The front and rear washer system share the same washer reservoir and a bi-directional washer pump. The pump delivers washer fluid to the rear glass when the windshield wiper motor activates the rear washer relay, which provides voltage to the washer pump. Ground for the washer pump is provided through the washer relay which is internal to the windshield wiper motor.
