Sounds like a short as defiance said. I could almost garuntee you've got a ground off or a rubbed through wire. Run down all your grounds and power wires. Looks like your gonna have fun pulling your loom apart and tracin wires back. Lol. This sucks man. I did it for 6 1/2 hours the other night to track down a simple little problem. Absolutely sucks

 

guess ill start there just try and get the lights wokign then go after the windows

 

beleive it or not both low beams in the headlights were burn out iv got power to the lights now ive just got to figure out why the lead coming into the fuse for the ins light has no power and why the windows still dont work. but one thing at a time

 

got the headlights working. and inst lights now still can get the windows to work. Ive got power coming in and good ground. When i jump the wires puting 12v to one and ground to the other i can get the windows to work. plug the master window switch in and doesnt work. Took the one out of my wagoneer and put it in the cherokee and still doesnt work??? i m gonna look at the the wire diagram again. let me know if you got any ideas?

 

still no power windows. got power,got ground even tried a master switch i know works and nothing. I am agle to jump a ground and power over and get the windows to move but any ideas?
