I have an 82 Vanagon GL Westfalia, and every since I bought it used 1.5 years
ago, sometimes, when I turn the ignition too fast, or if it's just feeling
rebellious, the horn will honk by itself.  When it happens again, just turn
off the engine, turning the key all the way off, and SLOWL turning back on
again.  Good luck.  David.

At the same time frame I had stuck a map light in the cigarette lighter. So
I stopped using the map light (from Walgreens) and took the fuse out for the
horn. My question is, is use of the map light and the horn malfunction a
coincidence, or are the wires related and is the map light too much? Either
way I later found some torn copper shavings from a flat-disc-metal-piece in
the horn. I still have them if anyones interested. >>
