So ive searched and found many answers but none that will solve my problem...

I have a 91 Bonneville and the power windows just stoped working and they wont go up or down from any switch. The locks still work just fine and all the fuses are fine. I took the master switch out to check for power behind the switch and each lead, when i press any of the buttons on the main switch, make the test light turn on. Meaning there is power to the switch and power going out of the switch. Any ideas? Is there a relay or something? I read somewhere about a module in each door but I didn't know cause that was for a different year. HELP ME PLEASE

Thanks guys.

There may be wiring problems.
