03 6spd duallie,radio was working intermittently 2 weeks ago,took the engine fuse box out and cleaned the terminals reinstalled with di-eletric grease,worked fine,made a 20hour drive to tennessee and back last weekend,no issues left for work mon morning worked for about 1/2 then started coming in and out then fianlly nothing.last night i left the door open while i was working on the fuse center and noticed that the done light would flicker on and off while i was removingb the box,so i know the issue is there somewhere,then nothing no dome light,key fab,power locks and couldnt get them back on?????any ideas?seems like there is a broken wire somewhere but i have no idea where to start,wiring diagram of the fuse center would be great

 

Would it be the wiring harness on the opened door???

 

Check the IOD fuse in the fuse box.

Here's the wiring diagrams for the 2004 model. http://www.dodge.com/bodybuilder/200...wd/drwd/tc.pdf

more than likely a bad ground. check and clean all grounds. also wiring harness that goes from the body side thru the rubber boot into the doors are also known to have broken wires (from opening and closing the doors so often).
