no power to window switch

I have a 88 trans am with power windows and recently the windows stoped working. I cant figure out why they would work albeit slow but still worked then the next time i go to work on it they dont work. I checked the fuse but its fine. I pulled the switch and checked with my meter and i dont have any power to any wire in the switch connector i am lost. Every thing else works.

"JUMP" the power window motor with power and ground to be sure they still work. Very possible your failing window motors finally gace up and died.

Re: no power to window switch

we finally fixed the problem. After checking power to the fuse box as suggested we took the fuse block loose to get a closer look and noticed a heavy pink wire unplugged up behind the fuse block so we plugged it in and everything works as it should. Thanks for the help.
