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 POWER WINDOWS - DIAGNOSIS AND 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.
1. Check the circuit breaker in the junction block. If OK, go to Step 2. If not OK, replace the faulty circuit breaker.
2. 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 Step 3. If not OK, 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 only). For
diagnosis of the driver side power window switch (Refer to DOOR MODULE - DIAGNOSIS AND TESTING). Unplug the wire harness
