I have a 2006 Ram 3500, when I bought it I didn't have this issue. I took vehicle into dealer for something and they updated computer. Now my horn blows as if it were a back up beeper when you are backing up with the door open. I have a hard time backing my trailer into a tight spot with door shut and if I open the door, the horn blows and bother neighbors now.
Is there a way to turn this off? The dealer tells me there is no way to deactivate it now.
