Door ajar warning light comes on and stays on even though all doors are secure.Sometimes the warning light goes out, only to go off again when car is locked 4 the night triggering car alarm.My guess is the door switch shorted, but cannot locate where they might be? Thanks 1 million:)

The switch or wiring at one of the doors may be bad allowing light to stay on .

Look for a contact switch in the trunk. Sometimes, when the trunk (or door for that matter) gets slammed, then button gets set deeper.
What's happening is door and trunk switches are "self adjusting", and a slam "Self adjusts" too far. It is hard to reset the switch without killing it. Just get another one if you find this to be your situation. Test the switch before you buy a replacment.

I suspect you have a bad door ajar switch on one of your doors.

The switch is on the door latch. try pushing each door in with your hand one at a time and see if the warning goes away.
The Lighting control module is $500 and controls a lot of the vehicle functions. It is part of the headlamp switch. It has to be configured by the dealer with his NGS tester before it will work. Ebay has them cheap sometimes. Only buy Continental LCM for your model year.



info
When at least one door is ajar and the key is in the RUN position, the door ajar cluster lamp is activated and remains on until all doors are closed. A warning tone will sound once any time the key is in the ignition switch and any door is open.

sound like your fluid sensor may be stuck or bad if light stays on try tapping the washer motor on the resevoir if it goes out faulty sensor as for the door ajar light it might have bad connection with sensor saying the door is closed local dealer should be able to troubleshoot sensor

I have this same problem. A mechanic friend told me that basically the grease they use to grease the door latches cause a sensor to think the door is open. He said to buy something thtat will break up this stuck grease, but also has lubricating effects. I forgot what he told me to buy though.

yes i agree with ripoff, If you are unable to do it yourself , then I suggest you go to a regular shop, and they should replace it with minimal cost, buy the part for eight dollars and bring it with you to the shop so that all you have to pay is labor, if it is really easy like i suspect you may not be charged at all, or even ask one of the guys if you give them a couple of bucks will they switch it real quick.
hey, I would do it..

the door pin/button could have been damaged you should have them replaced

If I am not mistaken, the plunger is located in the door with the latch. Most of the time you can just pull the door panel off and adjust the switch. After opening and closing the door, they get knocked out of adjustment. I sincerely hope that this helped you. Take care and best wishes.

there should be a switch mounted( or more than one) in the door jamb that tells the car when the car door is open...i will probably look like a little plastic plunger...might be broken off or bad internally

I had this problem on my 2003 explorer and took WD40 and gave the lock mechanism a good dose where it meets the clasp on the door jam. Then open and close the doors a couple of times to get them working. They get gummed up and sometimes have a tendency to stick.
