I was told that the dirty door sensors are causing the vehicle to think that the door is ajar. How do I fix this problem or eliminate the noise alert, it is non-stop.
Do you
have the same problem?

The switch is part of the latch assembly on your vehicle. You need to remove the door panel to access it. At that point you can check to see if the switch is bad or dirty. Here are diagrams below to help you change it out. Check out the diagrams (Below). Please let us know what you find.

You said that the latch is part of the door assembly, the ford mechanic said it is generally dirty and there is no way to really fix it. Is there a way to deactivate the door ajar alert? Maybe one of the fuses?

There is a fuse, but it will disable other things too. As far as the switch, is there a reason he can't clean it?

Stuck or faulty door ajar switch most likely culprit. Lubricate all door latches including rear hatch with WD40 to see if it will loosen the switch.

Yes switch is in door latch
If you have an access to a scanner, check BCM codes
Or data it should show which switch is at fault
99% of the time WD40 or penetrating oil worked for us

All doors are closed tightly how ever at times the door ajar will keep going on and off just like a door was being opened and closed.

You have a sticking door ajar switch. There is a switch in each door, as well as a switch in the rear hatch and rear glass hatch. Try lubricating the door latches with WD40.

About 3 months ago the door ajar light on the dash would stay on even after checking all doors and windows. After a couple of days it would go off. Then it got progressively quicker between light on and light off. Now it is continuous for the last 2 weeks. I had my oil changed and they checked the battery and said it was bad, only 2 1/2 months between oil changes when it was good. Is this draining the battery and can I check to see if one of the door sensors is working and replace it my self? Thanks for your response, Rahn Bergee

The switch is part of the door latch. As far as checking, you need to check if there is a draw on the battery after everything is off. Here is a how to for checking. Check it and let me know what you find. NOTE: If there is a draw, remove one fuse at a time to determine what circuit the problem is coming from.

This is a common issue with the newer model Ford trucks and SUVs. One of the door ajar switches, 1 located in each of the 4 side doors as well as 1 in the rear hatch, has failed. You will have to test each switch to see which one needs replaced.

Thanks for using 2CarPros. Com!
