Master Switch Input Test

4-door

NOTE: The power window control unit is built into the power window master switch, and it only controls the driver's window operations.

1. Remove the door grip cover.




2. Disconnect the 20P connector (A) from the master switch (B).
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, make the following input tests at the connector.
- If a test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the power window master switch must be faulty; replace it.




4. With the connector still disconnected, make these input tests at the connector.




5. Disconnect the 20 P connector and make these input tests.
