Test Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers on the diagnostic table.
- 2: This step will determine if the rear wiper operates properly when only the rear window washer switch is activated. When the rear window washer switch is operated with the rear wiper switch OFF, the rear wiper should wipe the window 3-5 times and then park.
- 4: This step helps to pinpoint the specific malfunction. The Park mode of the rear window wiper may be the only feature malfunctioning. When the rear wiper switch is ON, the rear wiper should stop at the parked position in between the timed strokes of the wiper. When the rear wiper switch is turned OFF, the rear wiper should park and remain in the parked position until either the wipe or wash mode is operated again.
