That's what I started with. By any chance did you short the button from the center of the column (horn contact) to the center shaft the wheel connects to? What about to Ground? This would eliminate the button, switches, and that you have a good ground.

I don't have a manual yet to investigate the wiring but just trying to work via elimination?

You cleaned the contact button and saw the "spring action" on it I was talking about so it was not frozen. Just under the column you can disconnect that button and touch the wire to any ground and the horn should go crazy. If not you don't have power to it. Then you would need to check power to the circuit.

I found this simple diagram that might help.
