Wiper and Washer Systems: Description and Operation

WIPERS AND WASHERS

The wiper and washer system consists of the following:
- Rear window wiper blade
- Rear window wiper pivot arm
- Rear window wiper motor
- Smart junction box (SJB)
- Washer pump
- Washer reservoir
- Windshield wiper blades
- Windshield wiper mounting arm and pivot shaft
- Windshield wiper motor

- Windshield wiper/wash switch (part of the multi-function switch)

NOTE: The SJB may also be identified as the generic electronic module (GEM).

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 and the headlamp control is in the AUTOLAMP position. When the wipers are turned off, the exterior lamps will remain on for 30 seconds before turning off.

Windshield Wiper/Wash Switch
The windshield wiper/washer switch is an integral component of the steering column multi-function switch. Refer to Ignition Switch.

Windshield Washer Courtesy Wipe
When the front windshield washer system is activated, the wipers will cycle 3 times with washer fluid followed by one final courtesy wipe a few seconds later to clear any remaining fluid that is dripping down from the top of the windshield.
