wd40 in all door latches and strikers.
You may have tried this but i have a 2000 expedition and when it sayd door ajar its usually the window part of the hatch that's open....other than that I dunno
Fix a "door ajar" on Chevy Impala 2003 . Still on doors closed.
I had a problem with my door ajar switch staying on in a 98 EXPO and when I took it to the dealer they just sprayed W-D 40 in the locking mechanism for the door. I guess there is a senso in there that turns the door ajar light on and the w-d 40 makes it get contact.
Try spraying the 'button' located in the door jamb and working it. See if that helps.
If your interior light is also on, replace the door switch.
the door ajar switch is Incorporated into each door latch if you have a problem with the door ajar light staying on along with the interior and running board lights spray each latch including the back glass and door latches and open and close each door several times this should fix the problem good luck
Ajar is the term for a door that is slightly open.
The Door ajar light is not run by a specific fuse. If your 2003 Kia Spectra has a door light keep coming on, you will want to check the connections to make sure that all of the doors are completely closed.
dirt gets into the door ajar switch, located on the backside of the door latch. To fix it, usually all yo have to do is go around to all the doors, spary a whole bunch of rustt penetrant like WD-40 into each latch mechanism, and open and close the door a whole buncha times. That usually knocks the dirt out of the switches.
The "Door Ajar" warning means your door is not shut all the way.
The door ajar switch is part of the latch, inside the door.
On my 2002 sportage 2-door, the door ajar light stays on when the tailgate is not locked. with the key.
