Well anybody thats had a second gen CRX knows it has TWO, yes TWO seatbelt lights (one on gauge cluster,and one on headliner.) and has a door ajar light on the gauge cluster. It also goes BEEP BEEP BEEP really loud when these lights come on,..

So you geussed it, I'm cruising yesterday, door shut, seatbelt on, and it keeps BEEP BEEP BEEPing for the door or the seatbelt (drivers side) randomly. Its really loud,and annoying.

Any ideas where to start?

Try under the seat, should be a harness from the seat to the carpet and disappear, jump the wires or see if its disconnect. There is also a sensor right by the weight sticker or vin plate (door section). It's like a L shape. Try pusing it back to see if the beeping goes away, the door might not push it back enough or if it is then replace it.

Thanks, will do and let you know.

I'm tempted to just yank the bulbs and find the thing that actually does the 'dinging'

koo, keep us posted

Lol My brothers old ED had the same problem.But it would come on when he hit the brakes.So we just took the mirror off and disconnected the lil beep thing.Also with his prelude it was like that.
