I found on this site it is a common problem.My wifes 02' had the door ajar light on and dome lights would not go out and chime would work erratically.Took WD40 and sprayed the lock latches on the four doors and the problem went away.Guess the contacts on the switch on one of the doors was dirty.
same thing happens to my wife's 03 4.0 AWD. I sprayed WD-40 in all the latches and ajar light went away in a second. I still don't know which door latch actually caused the problem. I guess that next time I will spray only 1 latch each time and see what happens.
