The door open dinger on my 2001 F-250 drives me nuts! I don't need a dinger to tell me that the door is open. I easily unplugged it on my 97 250, but I have not been able to find it on my new one. Anyone figured out how to get rid of the noise?
If you look in your owners manual it will give you instructions on how to deactivate your dinger. I read it about two months ago and can't recall exactly how the sequence goes, but it involves turning the key on and off and the headlight switch on and off in a certain sequence. Hope this helps..
