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.
The back hatch may be ajar.
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.
wd40 in all door latches and strikers.
door ajar means one of the cars doors are not closed all the way in ture this will keep your dome light on
If your courtesy lights are staying on with the doors closed and there is no door ajar warning light , check on your dash to the right of your headlight switch. There is a dimmer wheel switch for your guage lighting , if it has been rotated all the way up that turns on your courtesy lights when the doors are closed
To the right of the headlight switch is a gauge light dimmer wheel , if that has been rotated all the way up , your courtesy lights will stay on with the doors closed. If you also have a door ajar light lit up in your gauge cluster , then you may have a sticking door ajar switch , or something isn't closed properly
spray wd40 in all the latches then open and shut all the doors a couple of times
If they say on, that mans you have a door or rear lathcing liftgate/door that is ajar...make sure ALL doors al completely closed...if they are...you maight have a door switch that is faulty.
If your interior light is also on, replace the door switch.
Basically, although all other doors are shut, there is still a small draft which is coming in through the closed door, causing another to open slightly.
Possible faulty door switch.Try contact cleaner or light grade of lubricant on the switch. Push it i nby hand and see if door ajar light goes out.
