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 (Steering Column Control Module). 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 (Battery Junction Box).

Wiper/Washer Switch

The wiper/washer switch provides the following inputs to the SCCM (Steering Column Control Module) 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.
