hmmm, now thats an interesting problem. Have you messed with any of the wiring recently? like installed any new electrical components? (anywhere in the Jeep) like an alarm, Cb, stereo anything like that? If so, you (or the installer if it was done by someone else) might have accidently spliced into something they shouldn't have. let me know if anything was put in recently so I can get a better Idea of what you should look at.
