My truck when I'm driving well start making the beeping noise that comes on if u open the door but it's closed ! Some times it dosent some times it does it's seems like it only does it if I'm driving for a wile ! Does any one know y this is happining and how to stop it?

the door latch is most likely not making a full connection when closed, so it "thinks" it's open. spray some WD40 into the door latch, then open and close the door a few times. See if that eliminates the"Beeping noise" when the door is closed.

the "closed/open" sensor is on the door mechanism they go bad, mine did it, I cldnt get to the clip to unhook so I cut the wires, cause the door dinger stayed on and the dome light..

You guys are whiners. my F100 has dual buzzers. Not dingers, actual buzzers. One for headlights on, and the other for seat belts.

As for the beeping, could be two things. As mentioned, the door switch.

Or, could be the sensor that your passenger side airbag is turned off. I had this problem with my old Ranger. Tried spraying WD 40 into the door latch, but that didn't help. Somebody told me to turn the airbag on, and that shut it up.

lubricating didnt help my problem, hince the wire cutting
