'77 horn issue
'77 Horn Issue!!
--------------------------------------------------------------------------------
A coupla days ago, sitting in front of my house, my '77's horn started blasting non-stop for no reason. After five minutes of this, i realized it was my vehicle making all the racket, panicked and ran out wondering why and what i could do to stop it. Try as i may (including looking, to no avail, in the manual for the fuse location) i could not stop it. Irate neighbors looking on, i finally pulled the wire off the ramaining blasting horn (the left side horn having stopped. i presumed it had burned out as i could smell burning wire) and the blasting stopped!!! I now have no horn.
Can anyone tell me why this happened and what i can do now to restore horn use? Thanks, D.

Your problem is most likely caused by broken plastic rivets in the horn button contact. (see image below)
The contact is in the center of the steering wheel and is the part that the horn button is attached to. A new horn button contact is available from most vendors for around $20.

Not sure. I have personally seen it happen while driving through a parking lot. However, it is easy to tell. just pull the horn button off and inspect. Actually, you really only need to try and move the horn button. If it is fairly rigid it is probably fine, if it flops around easily the rivets are probably broken. They are plastic and become brittle with age.
