Master Switch Input Test

Master Switch Input Test

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 instrument panel.




2. Disconnect the 14P 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, go to step 4.




4. With the connectors still disconnected, make this input test at the connector.

- If the test indicates a problem, find and correct the cause, then recheck the system.
- If the input test proves OK, go to step 5.




5. Reconnect the connectors to the switch, and make these input tests at the appropriate connectors.

- If any 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 the switch.
