If you have a FJ Cruiser and the door ajar light stays on in the dash like this.... Then you will want to check all the doors are shut tight Including the Rear hatch Glass.... there is a switch in the latch that tells the cluster this door is shut. People usually forget to check the rear hatch glass. If you insert your ignition key into the rear hatch, turn it clockwise and hold it there for 1-2 seconds, then the rear glass will pop open.....
