ok when you are sitting in the truck with it running and hit the inside door lock button all the doors lock, and then the driver's door will unlock. When you put it in gear it doesn't lock the doors, and pops up on the DIC that the left rear door is ajar. I'm assuming it's doing this because the rear door is not registering as closed. When you try and use the key fob outside the truck. Push it once and it won't lock it just dings three times like a door isn't shut. Push it the second time, and it will lock. So basically the rear door is closed, but something is telling the truck that it isn't. I use the dome light override switch to turn the dome light off because it won't go off.

So I am just thinking that maybe the signal is going through somewhere else before it gets to the rear door. Everything was working fine, and then one day bam having this problem.
