Power Window Switch

For complete circuit diagrams, refer to the appropriate SYSTEM WIRING DIAGRAMS article. 

The front door power window switches are included in the window/lock switch  (Refer to POWER SYSTEMS/SWITCH - WINDOW/DOOR LOCK/DIAGNOSIS AND TESTING/ SWITCH - WINDOW/DOOR LOCK  ). 

The Light-Emitting Diode (LED) illumination lamps for all of the power window switch knobs receive battery current through the power window circuit breaker in the junction block. If all of the LEDs are inoperative in the power window switch and the power windows are inoperative, (Refer to POWER SYSTEMS/POWER WINDOWS/DIAGNOSIS AND TESTING/ POWER WINDOWS  ). If the power windows operate, but any or all of the LEDs are inoperative, the power window and lock switch units with the inoperative LED(s) must be replaced. 

1. Check the fuse and the circuit breaker. If OK, go to step 2. If not OK, replace the fuse or circuit breaker.
2. Turn the ignition switch to the On position. Check for battery voltage at the fuse in the Integrated Power Module (IPM). If OK, turn the ignition switch to the Off position and go to step 3. If not OK, check circuit breaker and repair the circuit to the ignition switch as required.
3. Disconnect and isolate the battery negative cable. Remove the power window switch from the door trim panel. Unplug the wire harness connector from the switch.
4. Test the power window switch continuity. See the REAR POWER WINDOW SWITCH CONTINUITY CHART  chart to determine if the continuity is correct in the Neutral, Up and Down switch positions. If OK, (Refer to POWER SYSTEMS/POWER WINDOWS/DIAGNOSIS AND TESTING/POWER WINDOWS ). If not OK, replace the inoperative switch.
