spray your door latches with wd40.
I've had that happen in my 2002 mountaineer. what I've found is that if you spray the door latches with wd40 it will clean off the sensors and the door ajar light should go out. but make sure all the doors are shut.
The door ajar light might stay on in a Mercury Mountaineer if a door is not shut properly. Sometimes a door will seem like it is shut, but will not be shut enough to trip the light off. Check for dirt or other debris in the door latch for all doors.
Close it hard
dirty door latch clean with wd 40
On my 2002 sportage 2-door, the door ajar light stays on when the tailgate is not locked. with the key.
Just spray some wd40 in all the latches. The sensors are in those latches. I had the same problem and it solved it for me
if you spray the latch inside of your doors with wd40, this should take care of your problem. Over time dirt build up inside causing the signal not to be received by the sensor. hope this help.
I'm having the same problem with mine and have yet to see a solution on the web. I hear ya man... I'm having the same problem with mine and have yet to see a solution on the web. I hear ya man...
