Wiper and Washer Systems: Description and Operation

Wipers and Washers

The wiper and washer system consists of the following components:

- Front/rear washer pump and reservoir (located in the front right corner of the engine compartment)

- Front and rear wiper pivot arms

- Windshield and rear window wiper motors

- Windshield wiper mounting arm and pivot shaft assembly

- Wiper/washer switch

- Front and rear wiper blades

- Body Control Module (BCM)

The wiper and washer system functions are activated by the wiper/washer switch which provides an input to the BCM (Body Control Module). The BCM (Body Control Module) then provides an output to operate the desired wiper system feature. The windshield and rear window wiper systems share the window washer pump and cannot be used simultaneously.

The windshield wiper system offers 4 wipe modes:

- Single

- Intermittent (6 settings)

- Normal

- Fast

When activated by the wiper/washer switch, the rear wiper offers 3 wipe modes which are based on the windshield wiper mode selected.

- 4 second rest between wipes (windshield wiper system in off or normal modes)

- Intermittent (6 settings based on windshield wiper system setting)

- Continuously (windshield wiper system in fast mode)
