There are door switches that cause the light to go off. Shut all doors and press gently on each door to see if the light goes out. If not then the door switches will need to be removed one at a time to find the bad one.
either the light is burned out or the door switch is sticking or malfunctioning. there in a screw right behind the switch on the frame where the door latches pull the little switch back and there is a screw there take it out and check the contacts they could also be dirty
Because one of your door sensors are broken.
some how the tail light wire is touching the ajar wire
On my 2002 sportage 2-door, the door ajar light stays on when the tailgate is not locked. with the key.
If the trunk lid isn't actually ajar, the switch has gone out of alignment, or it broke.
The back hatch may be ajar.
Fix a "door ajar" on Chevy Impala 2003 . Still on doors closed.
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.
The trunk lid is open or the ajar switch has malfunctioned.The trunk lid is open or the ajar switch has malfunctioned.
It's not a question !
If the door is ajar and light stays on, spray some WD40 into the latch. The door switch is probably stuck. Spray all doors then open and close a few times.
a door in your car is not fully shut.
