Rear Wiper/Washer Switch Test

Description:

Use these tests to verify proper wiper/washer switch operation after all wires are checked for continuity and the wiper fuse has been checked.
Before removing the wiper motor or controller from the vehicle, disconnect the vehicle harness from the controller and perform the "Wiper/Washer Switch Test."

With the ignition switch in "ACCY" or "RUN," probe the harness connector. All voltage readings are taken from the connector to vehicle ground.
