Do the interior lights work ok?
Check fuse #30 on the interior fuse panel. Replace if needed.
Pull out circuit breaker #10 and look for any burnt marks or overheating. Replace if needed.
If those are ok, next try with the key in the run position, and try tapping on the side of the master power window switch as you move the switches. If windows start to work replace the power window master switch.
Also try with the key still in the run position, opening and closing the drivers door slowly while operating the power window switch. If the windows work while open and closing the door, then there is a broken wire that is between the door and the body that will need to be repaired.
