My 03 Durango will only turn on my dome lights when the drivers door or rear hatch is opened. If I open any of the other passenger doors, my dome lights will not turn on. Where do I start?

 

i would start by checking the switches in the doors, and the wiring, and in the meantime i am going to ask if you have had any other weird electrical issues which seem unrelated (ANYTHING ELECTRICAL AT ALL???) if you have other electrical problems i would look into the CTM being the problem.

 

Does the "Door Ajar" light in your gauges come on when you open one of the other doors? If not there's your problem.

 

WhiteWidow00: No, the door ajar light does not work on an of the other 3 doors. I checked the 2 20amp fuses in the power dist. block last night, both OK. I think I might have it narrowed down to the CTM or a break in the tan/red wire. Should I try an impedance test on this wire? Can anyone tell me where the CTM is and how the wire travels through the vehicle?

 

Also, the only other electrical problem I have is that the drivers seat warmer stopped working. Passenger seat works (Wife's happy). I'm pretty sure I just need to roll the leather back and repair the broken wire.

 

yea the heated seat is a broken wire in the heater element, not related, i would check the wiring for a break before jumping to the ctm conclusion, an ohm meter will help alot with this, especially one w/ beeping continuity check

 

Thanks shrpshtr325, I'll see if I can find a break (I hope so). I'll let you know what I find. I appreciate the help.

 

I have the same problem with my drivers door. I'm pretty sure it's the part that lets the vehicle know when a door is open or not. Have yet to find a fix for this that doesn't require replacing the door latch.

 

The driver door ajar switch cannot be repaired and, if faulty or damaged, the door latch unit must be replaced.

 

Like hydra said the latch mist be replace. I would start by probably replacing a door latch on one of them (cost about 70$ for the latch and like an hour of your time) and if that works there's your problem.
