Power Window Switch: Testing and Inspection
SWITCH-POWER WINDOW
The front door power window switches are included in the window/lock switch.
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 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) must be
replaced. For complete circuit diagrams, refer to the appropriate wiring information.
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 power window fuse. 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 Power Window Switch Continuity chart to determine if the continuity is correct in the Neutral,
Up and Down switch positions. If OK, refer to testing. If not OK, replace the inoperative switch.
