Door ajar light stays on?

It sounds like the micro switch inside the latch on the drivers door is out try spraying the door latch with CRC, worked for me. FYI

As I turned off my vehicle and got out, I closed the driver side door and then opened the driver side backseat door. I closed the door and pushed the lock key on my remote twice. The horn usually honks once. This time the horn honked quickly twice. I thought this was strange and then noticed that the dome light did not go off. I unlocked the door, opened it, and then shut it again and pushed the lock key twice on my remote and the result was the same. I got into the vehicle and started the engine. The door ajar light remained on after the other lights went off. I got out and opened all doors, including the back window and tailgate door, and shut them all. The light still remained on. I put the vehicle in drive and moved forward a little and noticed that the doors did not automatically lock and they would not manually lock by pushing the buttons. I turned off the vehicle and waited a while to see what would happen. Over an hour later, the dome light was still on and the door ajar light is on when the vehicle is running.

I had a problem with 2002 Ford Explorer and was told to spray the door latch with CRC, and it worked for me.

My door ajar light is on as well as the interior lights, but there are no open doors. The interior lights stay on while I'm driving. Occasionally the interior lights turn off, but the door ajar warning light remains on. What does this mean and how do I fix it?

One of the switches on the doors (most likely the driver's door) is bad. The interior lights will only stay on for a set amount of time. The door ajar light will stay on the entire time you have the vehicle running.

Door light stays on when vehicle is running and all doors (including tailgate) are shut. Passenger-side window and lock controls won't operate, either. Was told it may be a bad door sensor, but my guess is that it could be bad wires. What do you think?

bad door sensor. spray wd40 onto all lock latches and open and shut them quickly to free up the stuck switch. this should take care of it

My light is staying on for a very long time it will stay on for 1 hour dont know where to stat looking
think you jamie

door ajar switch is faulty in one or more door jambs. try lubricate each door latch (including the rear hatch) with WD40 and work it in good. If this seems to help then you know it's definitely a switch. Will then have to test each one and see which needs replaced. common issue with these late model fords.

Door switches seem to be working.
I believe it is causing alarm to randomly go off.
Is there anyway to bypass the door ajar switches or can you just unplug them from the wire harness?
I did find a light blue and black wire in the driver side boot and i can't figure out where it goes to under the dash?

Hi,

I am not sure what the blue and black wire go to but it does not appear to be the door ajar switch. I attached the wiring diagram and that wire is not part of the system.

If you door ajar light stays on then it is either the switch or the wiring. This is a simple circuit so when the Security Module sees the circuit closed, it turns the light off. When one of them is open, the light is on.

Have you checked for an open circuit on that door?

This could explain why your alarm goes off at times because if the system is on and it sees a door open then it could turn the alarm on.

Let me know about the open circuit and we can go from there. Thanks

door ajar light always lit when no door is ajar constant clicking when driving from drivir side real and intermittantly the door ajar warning sounds from dash come on

The switches that control the lights for open doors are made right into the door latches and they have a history of sticking and causing problems like that.

Here is a technique that often works well and eliminates the problem at no cost.


Get a can of spray lube like WD40 or something like it and has a straw on the nozzel. Spray it generously up into the latch mechanism. Now open and close the door numerous times to work it in. Repeat this process several times. Since you don't really know which door is causing the problem, you should do all of them. It's usually caused by the most frequently used door but it's not gauranteed to be that one.

The door ajar light is on and won't go off. The interior lamps go off shortly after puting it into drive or will go off after 40 min when sitting with the vehical off to protect the battery. On most cars there is a little button you can just push in and it'll go off, but there is nothing. I looked in the repair manual and it doesn't say anything about it.
What do you think this could be?
Where are the door sensors?

very common. your problem is door ajar switch located on one of the door latches inside the door. what usually works is spraying wd40 liberally into door latch and opening and closing the door several times. ***the stuck switch is usually on the door that is least used like the passengers. let us know how you make out.

I have a 1999 Ford Expedition Eddie Bauer Edition.
I've been dealing this problem for months.
If I hadn't seen it myself, I wouldn't have believe it.
The door ajar light went out & so did the intierior lights. thanks tim your awsome !!!

good to hear, thanks

I googled this problem and this forum came up. Like magic it worked for me too. Thanks for saving me a trip to the mechanic.

your welcome

My door ajar light is staying on and the interior light won't go off. Where is the sensor for door closed on this model?

Hello I attached several pics. One shows you the location of where the switches are to give you an area to look at. I have also attached wiring diagram. There should be a push button type switch somewhere on the body, so when the door closes it pushes the switch. Some have a little rubber gasket over it. I have attached a pic to show you an example of a couple. The first is on a truck and it is a plunger on the side of the dash. The door hits it and pushes it in when it is closed. The other is on a car. I also gave you the fuse panel, if you pull fuse 27 that should turn your dome light off. Other things too though. Also, this does have a relay for the Interior lights. If you can not find a bad/broken switch, then check that relay. Hope this helps

Hey forgot a couple of the pics

I looked for the switch in the areas you are referring to and this model doesn't have one. This model has an enclosed circular plastic housing that a wiring harness feeds into and it is located on the door of the vehicle about half way up the front side of the door.

I have a repair manual for this vehicle but it doesn't refer to this problem.

i have seen this before on the explorer and what i have found is the door ajar switch located inside the door panel, mounted on the door latch gets stuck and what i have found to fix it is spraying wd40 onto latch and opening and closing the door several times usually will work the wd40 into it freeing it up. ***i usually find its the latch that is least used, like the passengers side. hope this helps
