instrument cluster died

I would get a wiring diagram of both the instrument cluster and the automatic headlights (i think thats what you ment). Trace the power flow and make sure its getting power all the way through. it could just be a ground or power wire that has some high resistance or got pinched. not sure why you checked the wires between the obd2 port and then instrument cluster immediately. if you are getting good power and ground to and from the instrument cluster then i would take another look at the wiring diagram and pay attention to the abs light and find out why that is illuminating but nothing else. I don't know if you have a scanner but i would plug it in to the obd 2 port and see if any codes come up. you can usually rent these free at shucks, orielly, checkers, or where ever you are near. im not really familiar with chrystler/jeeps but i hope this helps a little. wish i was there to help you figure it out. -PJ

Check the ground and all connections on the body computer located on the left hand fender well next to your air box...
