No horn. Where to look first?

[oooooh snap]

My horn would intermittently work/not work. I checked the connection in the fender well and it seems fine. After a few weeks of working on and off, it now no longer works.

I'm going to dive in to it soon, but was wondering if anybody had a similar problem, or has an idea of where I should start. :beer:

Test the horn itself with a temporary connection directly to the battery positive terminal.
