- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 5.
5. With the power window master switch 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, go to step 6.
6. Reconnect the 23P connector to the switch.
7. Turn the ignition switch to ON (II) to keep the system awake and perform the following input tests.
- If any test indicates a problem, find and correct the cause, then recheck the system.
