It is likely that one of your door switches is broken, shorted or just not closing far enough. First, walk around the car and push in on each door to see if the light will go out. If it does, adjust the lock on the door to hold the door in farther.

The interior lights and door ajar indicator are controlled by a combination of door switches. There is usually a centralized controller that receives ground signals from switches in each door, when opened. If any of the switches sends a ground signal, the controller turns on the lights.

If this doesn't work, find the switches in the door jams and check each one. Pull them out of the car body. If the lights go out, the switch is bad. In case the switch has two wires rather than one, pulling the connector off the switch should have the same effect. Test each switch in this way. If you have all switches disabled and the lights are still on, the problem is likely to be either one of the switch wires grounding out to the car body or the interior lights control module shorted on.

Please let me know if you have any questions.

    Check fuse 12. I've looked at the diagrams and nothing explainsto me why a power loss would put the ajar light on. The ajar switches appear to be on the locks themselves--inside the doors.
    I do not have diagram for the body control module. It may be the problem. Unfortunately, I cannot find an aftermarket part, and the BCM appears to be integrated with the fuse box. Hopefully fuse 12 is the issue. ;o|

    parts chain stores sell manuals, but it might not have what you need. None of them get inside modules like the body control. If you want to see something specific, I recommend a trip to the library. They have some of the big/more inclusive manuals. the dewey decimal for car manuals is 629. Been there many times.

I have a 2003 ford tauraus and when i start the car my interior light stays on and the door ajar pops on with all the doors closed and car running and then it does it after i get out the car it goes out...


That is because the switch is faulty and is not operating when the door is closed.

Hence the interior light stays on(unless you switch it off manually) and the warning system thinks the door is still open because the switch has not been activated and therefore the open door warning appears.

Hence you need to have the door operated switch replaced.

Door is showing open and interior lights stay on....when door is closed properly!!


This is because the switch mechanism on the door frame has failed and needs to be replaced. Hence the switch remains on and power will continue to flow to the interior lights until you switch them to full manual mode. The door warning light will also show as open because the warning light is operated off the same switch.

The interior lights stay on because the warning lights say a door is still open but it is closed. Is there any way i can disconnect the warning light, whats the best solution


Hi, There are several causes I would look for.
Each door has a door button that indicates if the door is closed, or turns on the interior light if it is open. There are also contacts on the sliding doors that when they mate, the warning light will go off.
I would try to find the cause.
Do the following.

1 Check to make sure all of the doors are closing properly. You may have one that looks like it is, but is not.

Each door that swings open, i.e. the two front side doors and the hatch should have button switches located in the front door jam of the front doors and one for the rear hatch. Somtimes you will find more then one button.

2 Close all doors
3 Open the driver's side door. (The one that gets the most use), turn on the key but DON'T start the car.
4 find the buttons and push on them on and off to see if the warning light goes out. If it does, then the switch on that door or the door closure position or latch should be able to be adjusted so it works again. If it doesn't, go to #5
(Note: the switch may have a broken off tip, so it may be necessary to replace it. )

5 Repeat for the passenger side door. If necessary go to 6
6 Follow test for the rear hatch. (you may need someone to help on this step.

The sliding door should have some type of "button" like contacts. There may be something lodged into one of them that is giving your a faulty contact.

Hope this helps,
Happy New Year,
Mark
