Power Window Circuit Breaker: Testing and Inspection
Circuit Test
NOTE: The circuit breaker is located in the fuse panel and mounted at the far left side above the parking brake release handle.
1.
Remove the power window switch bezel.
2.
Remove four (4) screws holding the switches to the switch plate.
3.
Separate the halves of the terminal plate by releasing the barbed hooks (this exposes the wire terminal ends).
4.
Turn the ignition switch to the ON position.
5.
Connect one lead of a test light to the black wire and the other lead to the red wire. Repeat this step with the second black wire in the master
switch.
^
If the test light does not illuminate, remove the test light lead that was on the black wire terminal and connect it to the chassis ground.
^
If the light illuminates at this time, an open exists between the master switch and ground. Fix the open.
^
If the light still does not illuminate, check for a defective circuit breaker or an open in the red (battery supply) wire from the circuit breaker to
the master switch.
