A couple months ago I noticed my display reading door ajar when the door was firmly closed, it was intermittent and only happen a few times. But now the damn door ajar beeps almost every time i drive it and keeps reading ajar when the door is closed. Has any one experienced this problem and were able to fix it? I attempted to look for the door sensor but I couldnt find it. Does any one know what type of sensor it is and where it is located? So I can fix it myself.. The beeping is driving me crazy!!!1 Help!!!
