Ok so my power windows in my 1990 xj dont work. I took off the switch panel on the driver door and then put it on my friends jeep and it made his windows go up and down so its not that. They havent worked since i got it and that was about 2 months ago and i would really like a nice fresh breeze lol. Would someone be able to tell me were my relay would be for my windows? Thanks

 

You don't say what year your XJ is in your avatar. It would be of benefit if you filled it out when asking for technical assistance. But on earlier models, the windows and door locks have a circuit breaker located on the bottom of the fuze panel. Both pull their power off the same circuit. One of the common things that happen is that the contacts in the plug get corroded and then things start quitting. They are brass, and will corrode. Get your terminals cleaned up an they will probably work.
