Sounds like a ground problem, that is if you checked the plug in at the jeep and all was good.

Check the plug that plugs into the Jeep. On mine I have one contact that wants to keep getting pushed into the housing, the retainer for the contact blade inside the plug is broke.

Previous Jeeps: 84 CJ7 (A True Jeep), 2000 XJ (163,000 Miles/Totaled (Pictures of wrecked Jeep in gallery)), 2004 WJ (parting out die to major electrical issues)

If you don't have time to do it right the first time, how do you have time to do it over.
