Ok, this problem has been ongoing for about 3 years now, not a real big one, but just gets annoying. My door ajar light will come on and stay on saying one of my doors is not closed all the way. Well I will get out of my truck slam all my doors and still it says door ajar. Light will turn off in the cab after going 15mph. But will turn back on will speeds dips below 15mph. It sometimes will be like this for a couple of days and then goes away. It seems to happen when someone opens my back door. Now when I have taken my truck to the shop, the problem never happens, so they say they can't tell what is wrong with the sensors or the problem. Any of y'all had this problem? Any feedback will be greatly appreciated.
