I had this problem on my 2003 explorer and took WD40 and gave the lock mechanism a good dose where it meets the clasp on the door jam. Then open and close the doors a couple of times to get them working. They get gummed up and sometimes have a tendency to stick.

there should be a switch mounted( or more than one) in the door jamb that tells the car when the car door is open...i will probably look like a little plastic plunger...might be broken off or bad internally

SOURCE: door ajar light stays on
go to your local parts store and buy a can of PB BLASTER lubricant then open each door and spray the latch assembley really good then close and open the door 10 to 15 times. do this with each door. the door ajar light switch is located in the door latch assembley and cannot be seen so soak the latch assembleys really good so lube reaches the switch. these switches sometimes get stuck but this usually frees up the switch

Your door lock module is bad. There are two ways to fix it. #1 is to replace the module. Various places online sell new ones for $160, while you can get them used for around $50. #2 is to replace the switch, which costs around $3-9, but then you have to remove the door lock module, remove the old switch, and mount/solder the new one in. You can also pull the door lock module and cut the wires going to the switch which will tell the door that it's always shut, and it will stop your dinging. That one's free, assuming you can get to the DLM.
