Power Window Switch: Testing and Inspection
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 both the power window and lock switch units and
the power windows are inoperative, refer to testing. 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) is faulty and must be replaced. For complete circuit diagrams,
1. Check the fuse in the Integrated Power Module (IPM) and the circuit breaker located near the park brake pedal. If OK, go to Step 2. If not OK,
replace the faulty 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 unit from the door trim panel (passenger doors). The drivers
door switch is included with the window/lock switch. Unplug the wire harness connector from the switch unit.
Power Window Switch Continuity Chart
4. Test the power window switch continuity. See the Power Window Switch Continuity charts to determine if the continuity is correct in the Off, Up
and Down switch positions. If OK, refer to testing. If not OK, replace the faulty switch.
