Diagnosis And Testing - Power Window Switch

Remove the power window switch. Refer to SWITCH, POWER WINDOW, REMOVAL AND INSTALLATION . Using an ohmmeter, refer to Window Switch Continuity Charts to determine if continuity is correct. 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 one 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. The LOCK feature for the rear window switch is internal to the master switch. If the Lock is engaged the rear switch assembly is disabled and will not illuminate.
