Diagnosis And Testing - Window Switch

For switch testing, remove the switch. (Refer to ELECTRICAL/POWER WINDOWS/POWER WINDOW SWITCH - REMOVAL) . Using an ohmmeter, refer to MASTER WINDOW SWITCH TEST to determine if continuity is correct. See Fig 1 and Fig 2. If the results are not obtained, replace the switch.

The master window switch has an Auto-Down feature. Actuation of the master switch to the second down position will move the drivers side window completely down. The electronic switch will automatically disconnect the motor approximately 1 second after the window bottoms out. Failure of the electronic switch to detect stall current, will cause the switch to disconnect after approximately 13 seconds. The auto down function can be canceled by any movement of that switch.
