Kudos to you Mike. A horn seems like a fairly trivial thing to have malfunction and a lot of people just pull a wire or a fuse and live with it. But it being there when you need it can be the difference in a life and death situation (plus it is illegal to drive a vehicle without a working horn). This is a good little write up on a repair that anyone could tackle. Only thing that you could add to the repair is cleaning the copper contact plate for a good connection.
