I have a 2003 ford explorer the door ajar light stays on but no doors are open and the alarm will go off for no reason, what could be causing this? Or how do I disengage the alarm?

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.

The drivers side door switch goes bad all the time on those, try replacing or check if its sticking.the small little button int the door jam.

ford have a inner switch that does not work with the door switch dome light. one of the switch could be broken.. most of the time it is the rear tail gate that give the problem..

Hi

there are small pin switches in the door, when the door pushes up againsit it in the closed position the pin switch goes in and turns the light off, if defective then they can stick internally causing this fayult, also there are 2 wires behind them that can corrode and start to decay, normally only one or 2 screws to remove the switches spray with wd40 any other faults would be obvious once you have removed it. there is one on each door including the boot although the boot / trunk will normally be seperate.

Hope this helps

Regards

Dan

p.s do you need any pictures ??
