Here is the problem. My dome light will not turn off when the door is closed, yes, i checked the passenger door. When i turn the ignition switch to acc, or run (but not starting) the dome light/console lights operate normally. When i turn the ignition switch to the off position the dome light does not turn off, but it dims when i depress the door switch. All new wiring using M&H electric. I used dielectric grease, and all grounds are to bare metal. I made sure all connections were secure. Also ignition switch, and headlight switch are new. I bought both from a reputable mopar vendor on escam(ebay). This is one subject that has pretty much crushed that dead horse

To me it sounds like a problem in the headlite switch rehostat. Think about where it gets its ground and power. Pull up a schematic and start with the easy process of elimination. Just because its new dont meen its good.

I would start one door at a time. Pull the switch and unplug the wires. Door switches should only have yellow wires on them. Tape them and leave them out of the system and see what happens.

The thing with the ignition is weird. The dome light circuit is a non-switched hot circuit and nothing to do with the ignition switch.

They do have the yellow wires.

Ok so isolate them one door at a time and leave them isolated.
Once you have done that with no change if any are piggy backed separate them and retest. Is there anything else on this car not working 100 percent? Auto or manual transmission?, Factory radio? Any other add on items like FM converter, tachometer, etc.

Do your dash lights dim with the headlight switch rheostat?

No dash lights, or front turn signals /park lamps. Headlights with relays work fine. I'm changing out the headlight switch. I ran the diagnostic with the yellow wires(door jamb switches) same result in the dome light staying on.

Ok if you did exactly what I said that eliminates that area. Next simple test is to unplug the headlight switch. No doubt you have other issues that most likely are not related. Did you verify all fuses with a meter or test light. Not a visual.

Yes, i used a power probe. The only wire that did not register was the tan wire on the headlight switch connector. Yes, used a power probe on the fuses, and they are good
