- Remove the steering column covers (see STEERING COLUMN REMOVAL AND INSTALLATION ).
- Disconnect the 8P connector from the wiper/washer switch.
- 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.
- Reconnect the connector to the control unit, and 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.
