Power Window Switch: Testing and Inspection
Switch Voltage Test
NOTE: The following tests determine whether voltage is continuous through the wiring harness to the power door lock switches.
LEFT DOOR
1.
Remove the door trim panel. See: Body and Frame/Doors, Hood and Trunk
2.
Separate the multiple terminal block on the wiring harness from the power window switch.
3.
With ignition switch ON, connect one lead of a test light to the black wire terminal and the other lead to the tan wire with black tracer. If the test
light illuminates, the wiring circuit between the battery and switch is functioning properly. If the test light does not illuminate, check the 30 amp
main fuse (circuit breaker) or check for an open in the wiring harness.

breaker) or check for an open in the wiring harness.
