I had the 'Corrosion problem' with my horn relay. I could hear the relay
clicking when I hit the horn on the steering wheel but no horn. Went to
install a new relay, but couldn't get the @#$%^&*( screw loose that holds
it on the firewall. So I soaked it with Rust-Off and reconnected the wires
so I could fix it later. On a whim, I was in the coach and tried the horn
which now worked perfectly. Went back to the relay and found that all of
the connectors were in sad shape. Replaced 'em and now everything is cool.
(Even have a new relay for the spares box).
