Well, it stopped the random honking, but I'm not really sure the culprit.
I got the little horn pad off, and removed the nut that holds the steering wheel on.
I thought I'd try "He-Man"ing the steering wheel off the splines, and I pulled and pulled, seemed to give a little bit, then I heard a noise.
A small noise, a tiny *pop* almost, if the radio had been cranked, I might have missed it.
Now the horn doesn't sound when the wheel is turned, but still works correctly when the button(s) are pushed.
Should I stop while I'm ahead, wait for the symptom to come back, or keep going looking for what the problem may have been?
What exactly did I do by pulling on the steering wheel?
