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.
Master Switch Test/Replacement
- Remove the switch panel (see step 12 on FRONT DOOR OUTER HANDLE REPLACEMENT ).
- Disconnect the 20P connector from the power window master switch.
- Check for continuity between the terminals in each switch position according to the tables.
Driver's 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 (see MASTER SWITCH INPUT TEST ). If the tests are normal, the driver's switch must be faulty; replace the switch.
Front Passenger's Switch:
Left Rear Switch
Right Rear Switch:
- If the continuity is not as specified, remove the three screws and replace the switch.
