Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnosis And Testing-Window Switch
For switch testing, remove the switch from its mounting, refer to REMOVAL . Using an ohmmeter, refer to Window Switch Continuity Charts to determine if continuity is correct (Fig 1 ) and (Figure ). 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 detent 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 15 seconds of operation. The auto down function can be canceled by any movement of the switch.
