Trying to chase this issue for the passenger front and driver rear windows on my 96 Yukon SLE 4Door. None of them are getting signal power. The power locks work. When I try to use the master switch, it sends out voltage to the signal wires but they still don’t go up or down. I’ve tried checking the window motor to see if it still works by manually supply power to them and sure enough they work. All the switches had been replaced, checked all the fuses and wiring, although I might be missing something from the doors that are inoperative. When I bought the truck none of the windows worked, I got them all to work before then these two windows decided to not work out of nowhere. Also weirdly enough, the moment I plug the switch in for the passenger front, the power door lock is illuminated, while the driver door’s isn’t, is this normal? Any help or ideas?
