Wiper Control Module: Testing and Inspection

Windshield Wiper Intermittent Control Circuit Input Test

1. Remove the gauge assembly.




2. Inspect the all connectors and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 3.




3. Make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the gauge assembly must be faulty; replace it.
