Re: where is the horn in my '78?
okay so i pulled the horn button assembly apart and i can make an arc between the sprung pin and the body ground.
i'm assuming that this is good because it means that i am getting power up the colum? *okay i put a multimeter on and i'm getting 13 v at the colum

Re: where is the horn in my '78?
Yeah it's above the fuse box.
Most of the time it's the horn ring in the column, but I've had a few of those horns go bad on me too. |

Re: where is the horn in my '78?
Put a test light on the horn wire and get someone to push the button.
I'll bet the horn is bad. |
