i recently bought a 1990 mustang w/ V8. problem is that sometimes when im driving around it starts beeping from some where under the dash and will sometimes continue for the whole trip. it drives me insane. any one know what it is, or where it is comming from if i could just disconnect it? it also beeps when i first start the car. thanks.

Do any lights come on on your dash with it?

Is it the ding for the door or for the seat belt?

if you start the car and let it idle will the beeping come on, or is it only when the cars in gear/moving?

This exact same thing happens to me. No dash lights come on. This happens to me whether I'm parked or driving but mostly just driving. It's annoying as hell. I had it in the shop for this and they said they couldn't find anything wrong, no bad codes or anything.

Ok it has to do w/ the air bag I think.Does your light on the dash for the airbag functioning.
And is it 5 successions of 5 beeps?

Pro, my air bag light flashes all the time (got so used to it that I forgot about it). I can't remember how many beeps though. I will count it the next time it happens.

is the "beeping" the exact same as the door chime or seatbelt chime? if so i had the exact same problem. I didnt think it was my doors because the light wouldnt come on but the chime would when i was driving. But it turned out the little button switch on the door was messed up, even when the button was closed it would have problems still. Try un screwing the button and unplugging it and see if it shuts off. Its real easy to do. If it fixes the problem just leave the switch out.

leaving the switch out won't fix the problem, the circuit has to be completed. when the door is open, the circuit is open. unplugging the button won't work.
