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.
On my 2002 sportage 2-door, the door ajar light stays on when the tailgate is not locked. with the key.
the door ajar switches are part of the door latch assembly in the door
AnswerIt is on the back side of the door latch assembly inside of the door.
Sticking door ajar switch ( mounted on the backside of the door latches inside the doors) or something not closed properly. To fix this, spray some WD 40 into the door latch assemblies, (all of them, including the rear hatch) and operate the doors a few times to free up the sensors.
i...i dont know. do you?
Because one of your door sensors are broken.
The door ajar switch is part of the door latch.
they are located on the door latches one on each side when you remove the hatch cover panel you can get to them easy.
spray your door latches with wd40.
I had the same problem with my 02 Ford Ranger the sensor is inside the door (genius idea ford). no amount of wd40 helped. luckily for me it was my passenger door. I just unplugged it and the dome light doesn't turn on for the passenger door but works find for the driver's door.
