I Figured it out.
I was actually able to trace the problem, thanks to a $10 voltage meter, to the rotary switch behind the steering wheel (see picture below). I dismantled the assembly and found that all the contacts had chewed themselves up somehow. Fortunately, I had an extra steering assembly that I pulled from a scrap disco I had last summer! You never know when you will need an obscure part like that. Kind of a weird issue but it's the first time I've ever come across a failure of this part. I'm just glad to have my factory horn back!
Thanks
