Wife took the 80 to a cruise in tonight and as she turned in the horn started blowing . It only does it as the steering wheel is being turned . The car has a telescoping and tilt wheel. Evidently there is a wire some where touching and grounding out to make the horn blow. Anyone had this problem for info on where or what wire to look at to fix this latest problem?
I've had this problem, but my horn was broken so I didn't hear it. Could be the plastic cylinder that holds the spring loaded ground, or the plastic "ring". Its been a while since I've been into my steering column.
It just happened here on my 76 after I had the steering box replaced with a Borgeson unit. It was fine for a couple of days. Then the OL and I left for a little cruise, and each time I turned the wheel, the horn went off. All the neighbors were looking and waving, and I was trying to figure out WTF? I pulled into the middle school parking lot and disconnected the horn wires. I would really like the horn back, but I'm not ready to tear into the steering column and screw that all up. I'm sure there is a wire shorting out in there somewhere. At some point when I get a few bucks, I may replace the Vega steering wheel with a real Corvette one and address the horn issue.

Don't leave it with the horns disconnected because if the relay gets a ground signal it will be on after you park your Corvette and either the relay will go bad or your battery will drain down.
Disconnect the BLACK wire at 'G' on the harmonica connection until you have time to get into the steering column.
Thanks Peterbuilt, Now, if you don't mind helping a mechanically challenged owner, where is the "G" on the .harmonica connection located. What do they look like? Are they down there by the horns? Do I just follow the wires to it?
After reading a little bit, it looks like the harmonica is located in the steering column. Is the relay to which you referred more accessible without having to tear into the steering column now. I followed the wires in the harness until they disappeared into the firewall and up into the steering column. Not something I want to get into right now. Damn.
Found the Harmonica, unplugged it and removed the G wire. Connection not exactly like the illustration above. On my 80 the connector holding clips are on the sides. Now the horn doesn't blow but I need a chiropractor. Thanks for the info guys
Well as I stated above the horn is not blowing now but I must have disturbed another wire. Now the turn signals don't work. What is the letter in the harmonic plug for the turn signals?
Went under the dash again, unplugged the harmonica connection checked the wires, everything looked OK . plugged it back up and the turn signals work. Must not have had it completely seated . I put a zip tie around it to make sure it was tight.
Sounds like you're getting there. Good Luck with the horn. I'm going to be troubleshooting mine today. Here's a link to Mr Shea's paper on horn diagnosis if you haven't seen it yet.
