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.

the problem is door ajar switch located on one of the door latches just inside the door. what usually works is spraying wd40 or an electronic lubricant prayed liberally into the door latch and then opening and closing the door several times. the stuck switch is usually on the door that is the least used door like the passenger side rear. let us know how you make out.

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.

if your door ajar light stays on, spray some wd-40 into the latch and work it a few times. the sensors tend to get stuck and a little wd-40 (or other lubricant) frees it up pretty good. A simpler check would be to make sure that the over head lights are turned off on the dash!!!

The door sensors will need to be replaced. A screws can be removed and then a wire can be taken of and you then can replace the switch.

Been having a problem with the dome lights on a 99 chevy blazer. Still can't figure out what the problem is. There is a dome light overide button located under the dimmer wheel. When I push the overide button in the dome light goes off, but when I open any of the doors the dome light will not come on. When the overide button is out the dome light stays on all the time and will not turn off even though every door is closed. I checked all the pushbuttons and everything tests good. Has anyone had this problem and know how to fix it?

next to the head light switch there is a roller switch. roll it down one click tell me what happens. sorry if you already tried this. good luck.
