All right, so the "Door Ajar" light will not shut off in my 2001 Ford Explorer Sport Trac (sp?), no matter what (all doors have been repeatedly checked and are securely closed). Dealer seems to think the controlling mechanism within the door is gunked up and therefore does not respond correctly within the door (seems to be the front driver's side door). This is probably a long shot, but does anybody have a suggestion, or a similar experience? Enlighten me. Trying to get the vehicle in tip-top shape for possible trade/sell.
