courtesy light switch , is door ajar switch an it's part of the door lock actuator . Light on coming on ? Not going off ? The ajar switch is a input to the GEM module , fords BCM - body control module . The GEM will energize a relay to turn on the lights .
The GEM will illuminate the interior lamps when any door is open or ajar. The interior lamps are; the dome lamp, the rear cargo lamp, the door courtesy lamp and the side rail lamps. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps will not be reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp switch is received.
The GEM controls the interior lamps illuminated entry function by activating the interior lamp relay.
Mite be a good idea to have it check for DTC'S - diagnostic trouble codes .

Most vehicle door open light works by a spring loaded contact switch. The switch body acts as ground. when the door is closed the switch depress disconnecting positive from ground. Seems that one of your door switch may be bad. Look for a rubber covered sitch on the door jam you should be able to remove the rubber cover to access the switch for a good inspection.
When my "door ajar" light was on it was because the liftgate sensors (switches) indicated that the gate was open, even thought it wasn't. I took off the plastic trim, and took out the sensors - but that isn't necessary. Just soak with the switches with silicone spray, and see if that helps. There is one on each side of the liftgate - I believe both must indicate "closed" for the light to go off.
I have gotten replacement motors at Checkers for both driver and passenger doors - so now I have lifetime replacement motors.. The first time you replace them, a little drilling is needed on the door sheet metal, but it will not show up once the trim is reinstalled. This repair is a little involved, but well within the capability of a novice mechanic.
If I am not mistaken, the plunger is located in the door with the latch. Most of the time you can just pull the door panel off and adjust the switch. After opening and closing the door, they get knocked out of adjustment. I sincerely hope that this helped you. Take care and best wishes.
one of your door pins are stuck . they are mounted inside the doors , they are attached to the latch plates. the trick is which one is bad .most times its the drivers side but not always.
good luck chris
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.
