This problem is caused by one of the door ajar sensing switches being defective, it is a common fault in Many Ford cars and light trucks. Each door has a switch and two at the tail gate door. The switches are attached to the side of the door latch and very hard to replace, since you would most likely have to detrim at least two doors to find the bad switch the most prudent thing to do is have the dealer scan the door ajar waring system, the scan will indicate exactly which switch has the problem.
Make sure all doors and trunk are properly closed. If light still stays on, you'll need to track down which door switch is causing the problem. Also make sure the interior light switch on the light controller is switched off.
buy a can of PB BLASTER lubrecant at your local parts store and spray all your door latches and trunk latch really good with it, then open and close each door 10 to 15 times this should free up the door ajar switchs that are stuck
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.
you may just need to adjust your door jams they may not be closing properly, the other thing you can try is opening one door at a time and putting your finger on the switch usually in the lower l/h corner of b piller and see if the light goes off if not this may be the problem and replace the switch
Remove "Door Ajar" switch. Clean the switch and use a graphite type lubricant (I recommend "Dry-Slide") to lubricate the actuator on the switch. Reassemble the switch.
The switches are located inside the door panels, attached to the catch mechanism.
1) Remove interior door panel.
2) Using a T-27 Torx driver, remove the 3 bolts holding the catch in the door. 2a) The door ajar switch is the only part on the mechanism with the 2-wire harness. 2b) The switch is located at the rear catch for the sliding door.
3) Using a small flat screwdriver, gently lift the black tab on the catch mechanism and rotate the switch to remove it from the catch assembly.
4) Using a rag, clean the small round actuator and apply a small amount of graphite lubricant to the actuator and work the switch so it moves freely.
