Question about 2003 Ford Expedition
This problem is caused by one or more of the 6 door ajar switches (one at each side door and two at tailgate) sticking in one or more of the doors, the tiny switches are attached to the door latch assembly inside the door, to ID which switch(s) is the problem a Ford dealer can scan the module that these switches send there signal to, this can quickly ID which switch is the problem, to guess would require every door come apart and each switch tested, this would be an all day job as the door panels and rear galss run channel must be removeds to get at the switchs

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

These switches are inside the doors attached to the door latch assembles.If you know some one with a scan tool you can go into the body computer and see which one is showing open when all the doors are closed. The most likly one is the drivers side door or the two in the rear gate. I've replaced those the most.If you don't want to replace them you can unplug them and the lights will go off. Hope this helps. If you need more info let me know> Thanks Dan

The door sensors will need to be replaced. A screws can be removed and then a wire can be taken of and you then can replace the switch.
