Every once in awhile on my 75 c20 the horn doesnt work but its a lose conection right where the wires go into the horn. I ussally can just pop the hood and push the wires towards the horn and it's good to go for a while. If that doesnt work hook and electric meter or smth t o see where u lose power at- see if u do have power at the plug by the horn or if u lose it at the fuse box.

You can run a jumper lead straight from the pos. terminal on battery to the horn and see if you hear anything....put your ear right up against the horn when you do this

I'll bet the horn is just shot. They may look pretty good on the outside but messed up inside. I have taken some off before that looked good but turned it upside down and rust came out
