Pinpoint Test F: The Windshield Wipers Do Not Park At The Correct Position




Wipers and Washers

Pinpoint Test F: The Windshield Wipers Do Not Park At The Correct Position

Normal Operation

When the wiper/washer switch is placed in the OFF position, the motor continues to operate until the motor returns to the PARK position and the internal Hall-effect sensor senses the motor magnet. The output to the integral run/park relay deactivates the relay and disconnects the voltage to the motor.

This pinpoint test is intended to diagnose the following:

- Wiper mounting arm and pivot shaft

- Wiper motor
