Wiper and Washer Systems: Description and Operation

WIPERS AND WASHERS

The windshield wiper and washer system consists of the following:
- Windshield wiper blade
- Windshield wiper pivot arm
- Windshield wiper mounting arm and pivot shaft
- Windshield wiper motor
- Windshield washer reservoir
- Windshield washer pump
- Check valve (integral to the washer pump)
- Multi-function switch
- Smart junction box (SJB)

If equipped with automatic headlamps, the SJB will illuminate the exterior lamps, including the parking lamps, when the front wipers are on for more than 10 seconds.

When the wiper control is set on any intermittent setting except INT 1, the speed dependant wipers will automatically adjust with the vehicle speed. This feature decreases the time between wipes when the vehicle speed increases.
