Test Description
The numbers below refer to the step numbers on the diagnostic table.
-
The passenger power window switch, on the master switch, shares a common RAP fuse supply voltage circuit and ground circuit with the left front window switch. If the passenger power window(s) operate properly from the master switch, the RAP fuse supply voltage circuit and ground circuit can be presumed good.
-
A short to ground in either power window up or down circuits would allow the test lamp to illuminate momentarily but would cause the PWR WDO circuit breaker to open.
