On an 84 Olds Custom Cruiser wagon where is the buzzer that sounds when you get out and leave the headlights on,it quit working, anyone out there know ?

 

It should be a chime module. It's located down by the fuse block mounted to the left side kick panel. I think this is interchangeable with most of the Olds B Bodies (Deltas, 98's, Custom Cruisers) from 1981-1984.
