Question about 2002 Mercury Mountaineer
Also the inside dome lights keeps flickering along with it---the door ajar light is lit and all of the doors are closed (including the hatch). This happened once before, took it to a mechanic but the problem never occurred with him so he stated that all he did was clean the door contacts and this worked for months.
One of your door switches is not completely closing for some reason. Try putting a sof shim on each switch, one at a time and see whcih one makes the problem go away. I would use one of those felt pads for the back of picture frames or chair legs to prevent scratching the floor.
One of them will solve the prolem and you can adjust the door or whatever to permanently fix it. good luck

I had the same problem. WD40 cured this in a flash! Be generous with the WD40 to allow parts to loosen and clean the "gue" that has built-up over the years. Several open and closings of the door should do the trick. Note that cold weather exasperates this condition. The best to you all in the new year!

The doorlach pin is faulty.
On newer vehicles it is inside the door on the locking mechanism.
It is stuck in the closed position, or has become dislodged.
Refer to your mechanic for repair.

Probably a door switch, check them first. Go to each door with a can of penatrating oil, find the switch in the jam, give it a shot and work the button manually until they're all freed up. Watch the light while you do this to eliminate which one's causing the problem. Please post your results.

remove the door switch, clean and reinsert. It switched ground to a black cable, which goes to the PCM.
