You have a short circuit somewhere in your dash cluster, when it heats up the wires probably soften and droop down contacting another wire and closing one or more lamp circuits. If you feel like taking the dash apart, get a wire location diagram and find the short, or take it to an automotive electrical shop.

Have tried several of these fixes...none seem to work - is there an actual fix?? Our 98 Windstar, when it is warm outside and we use the side door - the door ajar light comes/stays on and the dome lights...


I have a 2000 and the side door has four prongs sticking out of it, they are spring loaded. when mine messed up it was for the speakers. I took mine apart and fixed it, A spring had popped out some how. They are a simple setup.

How do I remove the door panel on a Ford F250 Supercab. I'm trying to find the switch for the ''doors adjar' light which won't go off and subsequently keeps my dome and outside bed light on and draws down...


the door adjar switch is the problem. the cargo light stays on until 35mph, as well as the overhead dome light. i just took the bulb out of the dome light and dont worry about the cargo light. it stays on for 30 min after the truck is turned off if the switch didnt trip properly. it shouldnt cause any problems as long as your batteries are good. i havent replaced the switch yet but it should be on the part of the door by the latch. get the replacement part and do a visual I.D. when you get the panel off. then replace it. the sensor is only 14$

Ford Taurus SE 1999. Dome Light - Door Ajar indicator problem. This is an intermittent problem, hence far more difficult to isolate. OK. I will be thorough in describing this "set of problems" as I do...


i must say that i feel your pain with this,, my door ajar light does the same thing but my dome light doesn't come on when the doors are open, i have to flick the switch on the dome light to make it come on. In my opion and i stress my opion it saounds like a issue with the body controller, im not sure what ford calls it but it controls all the body functions, i dont think the low coolant light is connected to the body contoller but i dont know this for sure, i think that light is controlled bny the engine ecm. some times a dealer can connect to the body controller and see if there are any fault codes for circuits that it controls and or monitors, also they can reflash or update the configeration and or calibration level cause ford release's fixes for issues all the time, same theory works for any control module on a vehicle. i dont think any of the auto parts stores have the right program to connect to bofy controlers but i could be wrong, worth looking into. i only put up with mine cause i use it as a beater, if you are worried about your dome light staying on and drianing your battery then you could pull out or disconnect the dome lights for the time being, its not a fix but just a band-aid.

Having trouble with door ajar dome light staying on when door is not actually ajar?


There is a switch that connects to the door latch inside the door. They can get sticky or come loose causing your complaint. Usually it is the drivers door since that door gets used the most. The door panel has to come off to access the switch. Sometimes you can remove the dome light fuse to take care of the light and indicator until it gets repaired.

2001 Sequoia, door ajar light goes off, but dome light stays on. Door ajar light comes on with slight pressure against closed door. Can replacing the door jam switch solve this problem? Why would the door...


To temporarily solve the light problem, I taped a washer to the inside of the door where the door hits the plunger on the light switch. A permanent solution would be to drill a hole in the door at this spot and put a self taping screw in that will trigger the switch sooner. I figured out the reason the dome light stayed on is due to the courtesy light timer and the lights would have eventually gone off.

2004 crown vic interior lights stay on


Don't think you have a door ajar switch problem , more then like the lighting control module is the culprit . Does the door ajar light on the instrument cluster stay lit ?
The interior lighting can be separated into two distinct modes of operation: the courtesy lighting and the demand lighting. The lighting control module (LCM) controls all of the interior lighting in the vehicle, as described in the following text.
The front dome lamps, rear reading lamps, and instrument panel courtesy lamps, can be illuminated either by opening any of the vehicle doors (courtesy lamp function) or by depressing the headlamp switch (demand lamp function).
When any door is open, the door ajar switch grounds an input to the LCM which then sends power to the courtesy lamps. The voltage sent to the courtesy lamps gradually increases from 0 volts to 12 volts within 500 ms (± 50 ms), to achieve the theater lighting effect. When the door(s) are closed the door ajar switch(es) break(s) the ground to the LCM input which then gradually reduces the power from 12 volts to 0 volts within 5 seconds. (± .5 second).
When the headlamp switch is depressed it grounds an input to the LCM which in turn sends 12 volts to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps. When the headlamp switch is depressed a second time, it breaks the ground to the LCM input which then ceases to send power to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps.

The battery saver will disrupt power to the courtesy lamps after 10 minutes, the demand lamps after 30 minutes, and the headlamps after 10 minutes. Turning the ignition switch to the RUN or ACC position will terminate the battery saver feature by disabling the interrupt timers and reinstate power to the lamps.

1997 Tarus dome light and floor lights will not go out.


This is usually caused by the switches sticking in the door latches. Try spraying some WD40 in the latches and open and close the doors a bunch of times that should take care of it.
