What would cause the door ajar light to stay on even after all of the doors have been secured?

Do you
have the same problem?

Spray some lubricant (wd40 etc.) Into the lock mechanism on the doors. The switch may be jamming up. Let me know

The front door entry system contains a latch that is fastened to the inside of the door frame and is controlled by the exterior and interior door handles. The latch contains a door ajar switch and a door lock actuator. The front doors can be locked/unlocked by the remote keyless entry (RKE) transmitter, the RKE keypad, the door lock control switch or the door lock cylinder.

While the door is shut the "door ajar" light will stay on, on the dash and the dome light will stay on in the truck. What do I need to do?

If I recall, the door switch on this model year is actually part of the door latch. Check there to see for it and check to see if it is in need of adjustment or if it needs replaced.

While driving my door ajar lamp stays on causing my interior light and outside cab light to stay on then when I'm parked and truck is off those two lights stay on until I finally unhooked neg. Battery cable. If I hook the cable up after few hours it resets the computer I guess so it works normal for about five minutes then the lamps come back on while driving. Obviously I have made sure all doors are closed tightly but it doesn't help

Have it scanned by a pro as it may be the body control module

Thank You
Would that also make it so the power locks don't work?

It cold but check the fuse and relay if it has one in the underhood box.

They can be tested but easiest way is to just switch it with a like relay

I have a 2001 f-150. The dome light, inside door lights, and the light facing the bed stay on when the doors are closed. The door ajar light goes off when the doors close. It does this while running and off just the same. I checked the fuse and the relay I was recently hit pretty badly on the passenger side. The passenger door was replaced. The problem started roughly a month after I got my truck back from the shop.
