My 2003 Durango will not turn on the overhead lights if the passenger door or two rear doors are opened. Drivers door and rear lift door work just fine. They will turn on if I press unlock on my key fob. Any ideas?

 

i would start looking at the switches for those doors and/or the wiring that goes to them (check the switches first)

 

I forgot to mention that they all stopped working at the same time. Could the switches still cause the problem?

 

I doubt it!

The switches and locking assemblies are all a one piece and have to be replaced as a single piece. I don't think that your issue is switch related, sounds more like a CTM in my book.

Remove the negative battery cable. Then I would take the drivers side kick panel off and check all the connections at the CTM first.

 

After testing the door ajar switch in the passenger door, we determined that there was a break in the tan/red wire which runs from the switch to the PCM. The tan/red wire looked good at the PCM so we started tracing the wire back. It runs From PCM down under drivers side sill, splits into 3 and continues to passenger and two rear doors. It was ovious once we removed the plastic strip on the sill. Years of Chicago winters allowed enough water to seep past the plastic sill cover and corrode the wires where they split from one to three. It was green from the copper oxide. Trimmed back the wires, soldered them back and covered with heat shrink. Everything works again.
