The door ajar light stays on indicating a door is not shut, but they are. Is there anyway to tell what door latch switch is not closing? (without pulling all the laches out.) I know the dealer could pull a code from the body computer but I wanted to try to fix it myself cheep. Any help is appriciated!!

This is going to sound stupid but what is the dome light switch on. Off, comes on when the door is open or On. I would check to make sure the switch isnt left on the on position.
