Hi, Mik; Thanks for getting back to us on the door wiring problem and this one, also. It really helps out others that may be experiencing similar issues. Thanks again.
I have a this jeep that when accelerating the engine and electrical system would cut out then back on, like the key was being turned on and off. After a little investigation I found the problem. There is a wiring harness that runs behind the valve cover the turns toward the front of the engine on the drivers side of the 6 cylinder engine. At the this corner of the valve cover ( driverside -rear) there is a bolt sticking up that the wire harness rests on. The vibration of the engine had wore through the covering and into the wires. I taped up the wire and put some space between the wire and bolt . That was 3 years ago and no problems .
