Door ajar problem

[Mike L]

I had my 2002 Mountaineer windsheild replaced. The new windheild had a water leak and the vendor repaired it the next day.

Ever since then my interior light stays on and the door chimes as if the door is left open when the engine is off. When I press on the rear defog my cluster displays that the door is ajar.

Does this look like a simple door jamb sensor problem or does it look like water my have got into the dash board and shorted something out.

Everything works it just annoying that I have to roll down the interior light button at night so that the light goes off.

My front passanger door did that for a while, I just sprayed some WD-40 in it and locked and unlocked it a bunch of times.... Hasn't done it for over a year....

Welcome aboard Mike L!

I had similar electrical issues with my 02 xlt. The dome lights would stay on until the battery saver feature turned them off, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, etc. Most recently all 4 windows stopped working.

A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I found 2 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal. When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ.

Could also be related to the door ajar switch.

Here is a great thread for checking/replacing the door ajar switch, thanks to borland for the awesome write-up: http://www.explorerforum.com/forums/showthread.php?t=249253

That is a great write up.

On a side note, before going through a complete replacement of the switch, you can spray WD40 into the door latch opening on each door, as these become stuck sometimes....and this can alleviate the issue.

This worked for me, after going for more than a year of the "door ajar" light coming on occasionally...mainly after a car wash, high humidity, or rain....making me unable to lock/arm the vehicle from the door keypad and keeping the dome lights on. Worth a try....it worked for me

Be sure to take your time when looking for broken/damaged wire(s). When you think you're done looking, look again. A bright flashlight can be very helpful.

Hope this helps out! :biggthump
