When you open the door, you should see the sensor, looks like marker cap sticking out either from the door or from the car body, check all around, and press it, do this to all doors and truck, if you have a station wagon. If the door ajar still doesn't stop, than you need to remove this and replace it, or you can super glue it and forget about it.
make sure ALL the doors are closed
Fix a "door ajar" on Chevy Impala 2003 . Still on doors closed.
The back hatch may be ajar.
One of the doors is not completely closed, or you have a faulty door switch.
door ajar means one of the cars doors are not closed all the way in ture this will keep your dome light on
If the lights are on and the door is ajar it will make a steady alarm.
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.
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
why does my door ajar alarm keep coming on and off while driving my car.
The door ajar switches are inside the doors mounted on the backside of the door latches
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
do you mean door ajar message? Open both doors and spray WD40 in door latch. Then open and close doors many times. This fixed my problem. Hope this helps.
