SOURCE: door ajar light stays on
I have the same problem with my passenger door all the time. The dealer was nice and didn't charge me for some advice. Find out which door it is or do this to all. It is the part on the door the grabs the round thing in the door jam. It looks like two fingers kinda. Spray with WD-40 and clean with a rag to get all the dirt out of there. Spray again and open and close the door several times. This clears my problem and I hope this helps you too.

SOURCE: Door ajar light
The sensor for the lights is in the door latch spray some GOOD penetrant in the door latch (WD 40 IS NOT A PENETRATING OIL!!!!!!!!!!!!!!!!!!) open and shut the door several times after you let the penetrant soak a bit Liquid wrench, PB Blaster, BG Penetrant, are good

One of your courtesy light switch's is defective, it can be in any of the five doors (rear hatch has 2), Ford can determine which one (courtesy light switch) is at fault by using a NGS (New Gen Star Tester) to monitor the switches through the Generic Electronic Module of your truck, these switches are attached to the door latch assembly and are time consuming to replace, so the Ford tester is the cheapest option.

The door switches are built in the latches on each of the doors, they are pron to sticking, leaving the security module to beleive the door is open.
The simple fix is to spray a generous amount of WD40 on, in, and around the door latches, then opening and closing the door a few times. I would start with the passenger door as`this is likely the culprit. do the rest of the latches as a prevenitive measure.
Hope this is of some help.

try spraying silcone spray in each door latch even the rear hatch door. i have done this before and it has fixed it before. the reason is that dash will get on the sensor and make the light come on.
