Power Window Switch: Testing and Inspection

DIAGNOSIS AND TESTING - POWER WINDOW SWITCH





Remove the switch. Using an ohmmeter, test the window switch for continuity in all positions listed in the Continuity Table. Refer to the Power Window Switch Continuity table to determine if continuity is correct.






To test the left front down and express down switch position, connect pin 4 to ground and pin 12 to a 12 volt source. Using a voltmeter, measure for voltage from pin 13 to ground.

To test the right front down and express down switch position, connect pin 4 to ground and pin 12 to a 12 volt source. Using a voltmeter, measure for voltage from pin 3 to ground. If the correct results are not obtained, replace the switch.
