In my particular car, it was a bad resistor on the backside of the instrument cluster.
Set the buzzer off, and the car wouldn't start without teh resister.
*grr*
I don't have teh car anymore, but if I ever have that jhappen again, I know what to do.
KILL the BUZZER!
;-)
It's not always that easy. I pulled the seat belt buzzer in another car and lost the interior lights. The bastards wired the light circuit through the buzzer. I mentioned this to the dearler (under warranty) and apparently they knew exactly what to do (they put in a jumper) and didn't charge me.
