Combination Switch Control Unit Input Test
Combination Switch Control Unit Input Test
1. Remove the steering column covers.
2. Disconnect the 8P connector from the wiper/washer switch.
3. Inspect the connector 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 4.
4. With the control unit still disconnected, 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 combination switch control unit must be faulty, replace the wiper/washer switch.
