Best find a Jeep forum and start searching. Jeeps can have some peculiarities with electronics. I know my dad had a Wrangler at one time that was giving problems because of a plug under the seat coming undone. His current '00 Grand Cherokee had problems related to a tranny speed sensor (which are fairly cheap for them).
