Window Gremlins - need help
After pulling my dash on my 1976 Stingray, dying the interior a whole new color and reupholstering my dash, during that time I went ahead and did some wiring troubleshooting and fixing from the PO's bubba style fixes. I got both window switches working great. While I was putting the dash in, I would periodically check to ensure they still functioned (my OCD) and after I got everything back in and installed, neither of them worked. Fast forward to this weekend, I decided to troubleshoot, since neither window worked firstly I checked the fuse, it wasn't blown, replaced it anyway just in case, no luck. Since neither were functioning with the switches, I went to the relay next, so i pulled it apart, cleaned the contacts, and bench tested it, it worked perfectly, thought maybe it was the ground bolt, wire brushed the mounting point and cleaned up both sides, no luck, so just to be sure, grounded it directly to the radio ground wire, still no dice. Next i pulled apart the window switches (drivers was OEM, passenger looks like an aftermarket) but i cleaned out all the buildup and crud, cleaned the contacts and verified they made contact from the rockers, re-installed and still no window function. I cleaned the wire contacts to the switches and even bent them in slightly more to ensure they grip the window switches, still nothing. Now i assume they weren't getting any electricity, so i checked the fuse again, and the wires coming out. Everything looks to be in good working order, plugged in correctly, no fuses blown, no wires cut, can't seem to figure this out. I know both window motors function, but since i don't even hear the relay click, it has to be somewhere between the power and the switches. Anything i may have missed? Thanks guys!

The fuse could be good but the contacts it presses into may be corroded. You can either use a spray contact cleaner or by a fiberglass pencil (auto parts store) and clean them up. It is a lot easier to use a test light or meter to follow the voltage from fuse to switch rather than cleaning and checking

the power window wire just pushes in the fuse panel, could you of knocked it out ? Since it was an accessory, they just added the power by pushing a wire in the fuse panel, it knocks out easily, ask me how I know.

I've checked the panel, no corrosion on the contacts, and i've gone through the wires a few times and made sure its seated properly in the fuse panel...

Not real familiar with your year,
The chrome cars have a relay under the radio. When the ignition key is on the relay allows power to the windows.
I would check the switch and make sure you have a live feed to the switch first.
There is also a circuit breaker on the firewall near the windshield wiper motor.
