Doors either have a switch that closes when door closes, or they send the message from the latch itself. Yours in new enough to maybe have it all in the latch. Look for a little button in the doorsill area that would be depressed when door closed, and springs up when door opens. If not, you have a door module (latch) that is not telling the Body Control software it's closed. Haven't isolated which door, yet? Start with the one that is used the most. The driver's door. Hope this is helpful. Post again if you need more troubleshooting tips. Thanks, TT

Spray some lubricant (wd40 etc.) into the lock mechanism on the doors .. the switch may be jamming up ..

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 .

Start at the driver's door; since this is the most used door. Disconnect door ajar swiches one at a time until the light is off with all doors shut. If the light is still on with all switches disconnected, there is a short circuit in the wiring somewhere. The most likely spot for a short circuit is under the carpet near the front seats.

Door ajar light stays on


Why is it that a door can be ajar but a jar cannot be a door? - Always wondered about that one....:)

On a more serious note: Ford Explorers are notorious for the door ajar switches going bad. I have seen them com on by themselves when the vehicle is parked and cause the battery to go dead because they will turn the dome lamps on also.

Most of the time it is the driver's door that has the problem, but ANY of the doors COULD be tha cause. It would be best to scan the computer system and look at the Generic Electronic Module (GEM) data to see which door is showing "open" when you have all the doors closed. Otherwise, you may have to disassemble ALL of the doors to find the culprit if replacing the switch in the driver's door does not fix the problem. The first picture below shows the switch itself. The second picture shows how the switch is mounted in the door latch mechanizm inside the door panel.

How do i slove my door ajar problem


Try spraying wd40 into each door latch. Do it one at a time then open and close the door about a dozen times spray some more in there after about 6 open and closes. Do this with each door and even the hatch. This should clear ya right up.

Dome light won't shut off after truck is off and doors are shut and door ajar light is on while driving but all three doors are shut.


sounds like one of the dome light switches is bad pop them out one by one and disconnect only one at a time until the light goes out or door ajar goes off, then a quick trip to the parts store and you are good to go! :) hope that helps

2001 Ford Escape, dome light will not go off when door shut, but door ajar light is dark?Could this be the door switch? are there different switches for the door ajar light and the dome light? How can I...


The door switch provides a ground to the dome light... so there is no danger to you if you want to attempt a removal of the switch. A rusted or shorted wire in the door switch (of any door) will keep the dome light on.

Door ajar alarm


The doorlach pin is faulty.
On newer vehicles it is inside the door on the locking mechanism.
It is stuck in the closed position, or has become dislodged.
Refer to your mechanic for repair.
