i just got a 90 si hatch and something is up with the beeper or the wireing to it when i hit bumps it starts beeping untill i hit another bump. some times it just stays on. its really really anoying i need to find it and unplug it.

 

The door / seatbelt beeper transducer (speaker) is up inside the plastic above the rear view mirror.....The key / ignition one is under the dash under the steering wheel?...good luck.......

 

cool thanks. i think its the door one cause the key one doesnt even work.

 

yep, up under the cover on the rear view mirror.
