NO POWER WINDOWS

1997 Cadillac STS • 285,000 miles

Hello, I have a 1997 sts. About a week ago my power windows started to hesitate. This was all 4 windows as well as the sun roof. Now none will go up or down. I checked the fuses in the trunk as well as the one's under the hood. All seem fine. Is there a relay or something else that may cause this? Thanks, Keith

At the hinge side of driver door, check the wiring harness. Pink wire is voltage, use a voltage tester, for power windows, black wire is ground.

Note the diagram. Remove power window circuit breaker, one leg should be hot all the time, use voltage tester.

Remove the window switch test for power and funcition. The master switch maybe bad.
