The horn circuit is the most complicated and confusing circuit in the whole 
car. Basically the horn is supplied power directly from the fuse box and its 
ground is switched at the steering wheel hub. 

The power side is direct and simple. It's the ground path that's complicated 
and that's where the problem almost always is.

Max didn't tell us where he disconnected the horn. If he simply removed the 
fuse, it's likely that this fuse also supplied other things and those other 
things are also likely suspects. If he removed a wire from the horn, then that 
narrows things down to the horn itself, or the long, complicated path to the 
steering wheel and to ground.
