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.
Power Window Switch
The Light-Emitting Diode (LED) illumination lamps for all of the power window and lock switch and bezel unit switch paddles receive battery current through the power window circuit breaker in the junction block.
If all of the LEDs are inoperative in either or both power window and lock switch and bezel units and the power windows are inoperative, perform the diagnosis for ALL WINDOWS INOPERATIVE . If the power windows operate, but any or all of the LEDs are inoperative, the power window and lock switch and bezel unit with the inoperative LED(s) is faulty and must be replaced.
- Check the circuit breaker in the junction block. If OK, go to next step. If not OK, replace the faulty circuit breaker.
- Turn the ignition switch to the ON position. Check for battery voltage at the circuit breaker in the junction block. If OK, turn the ignition switch to the OFF position and go to the next step. If not OK, repair the circuit to the ignition switch as required.
- Disconnect and isolate the battery negative cable. Remove the power window and lock switch and bezel unit from the door trim panel. Unplug the wire harness connector from the switch and bezel unit.
- Test the power window switch continuity. See DRIVER SIDE WINDOW SWITCH CONTINUITY CHART and PASSENGER WINDOW SWITCH CONTINUITY CHART to determine if the continuity is correct in the Neutral, UP and DOWN switch positions. See Fig 1 .
- If OK, go to POWER WINDOW MOTOR . If not OK, replace the faulty switch.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
