So when does the horn NOT work?
Help us help you. Put us right in front of your vehicle.
Do EXACTLY what I say on the post above, report back EXACTLY what you see, hear feel, smell (hopefully not smoke - LOL), and you may not have to tear apart the steering column parts.

I walked to the front of the vehicle, removed my grill, unbolted and removed the horn. I ran 12V directly from the battery to the disconnected horn to make sure that it worked. It made a noise.
I then placed my multi-meter probes on the connector at the front of the vehicle that connects to the horn, I had my wife press the horn button in the cab while I measured the voltage across the connector. It read approximately 0.2 volts (which i'm not positive isn't an error).
I then removed the steering wheel to check the pin. It is in good condition and making contact with the ring on the steering wheel.
I then jumpered the pin to the steering shaft (ground). No noise.
Using my multi-meter, I measured between the pin and the steering shaft and got a reading of 0 volts, with a jumper and without a jumper.
