One or more of the door latches are bad. The switch to turn off the dome lights are built into the latches. You can try spraying wd-40 or pb blaster into the latch openings and shut the doors quite a few times and see if the light goes off. It's a temporary fix. At least the light will be off and you will know which one is bad. Start with the drivers door. It's either that or you turned on the dome light switch on the dash or a button near the dome lights.

I have a 2004 Mercury Mountaineer, V8, AWD, My problem, I think is in the computer? When I shut the engine off and try yo exit and lock the vehicle, setting the factory alarm system it won't do it. The digital display says that there is a "DOOR AJAR". I have checked all the doors as bet I can and they appear closed. BUT the interior lights remain on and the alarm will not set because off the ajar message. Am I missing something? Is the computer having a brain cramp.? I can get the alarm to set if I manually shut off the interior/dash lights too off. then it will work but no interior lights on the dash. This is driving me nuts. Can uou help?Thanks,John 12 Answers
