I have an 86 Bonnie, and my signal lights are not working. I am mechanically inclined, but have little car knowledge. I know that it is not the light bulbs, or the fuse. I suppose that it could be the actual fuse box or the switch in the column. Does anyone have suggestions as to how to fix them?

Welcome, !

Don't the older cars actually use a flasher relay? Silver thingy in the fusebox? Do you have an owner'* manual that shows fuse/relay locations?

Hey, welcome to the club. Do you have any pics?

Anyways, it could be the mechanical flasher in the fuse box (the silver round thing), or it could be something broken in the steering column. I recommend if you change the flasher, get an electronic flasher. It will plug in exactly like the mechanical one but your turn signals will speed up. I had a problem with mine that they flashed so slow you couldn't always tell when I was turning. Hope you get it fixed. Good luck!
