Master Switch Test/Replacement

Master Switch Test

1. Remove the power window master switch.




2. Disconnect the 14P connector from the switch (A).




3. Check for continuity between the terminals in each switch position according to the table.

Driver's Window Switch

The driver's switch is combined with the control unit so you cannot isolate the switch to test it. Instead, run the master switch input test procedures. If the tests are normal, the driver's switch must be faulty.

4. If the switch is faulty, replace the switch.
