[Bagel]

Hi folks. I have a 1964 Grand Prix. It was sitting in a barn for the last 20-some years. We finally go it out and running last year with a lot of help from a local shop.

One of the things that I had my local shop replace was the horn. The horns always work when I push down the button. But occasionally the horn will go off when I'm turning. (It has happened when turning both left and right). It doesn't happen every time. In fact, it happens maybe once or twice a drive.

I have the "deluxe steering wheel" for my automatic. The only thing I think inside the steering wheel is the horn button and turn signal stalk? My understanding is that since the horn is a one-wire, all that it's doing is grounding the relays to trigger the horns.

Since the horn has only gone off while turning, my theory is that the wire in the column must be worn/damaged around the insulation and a piece is touching the steering wheel column to complete a ground. My local shop says that the button is good. But I think I want to try to fix this myself since they weren't able to give me a quote (due to all of the unknowns).

I have the 1963 & 1964 supplemental chassis shop manual that goes over the exploded view of the steering column. I haven't taken it apart yet, but I plan to very soon.

1. If it is the problem wire, am I able to disconnect the old wire from the back of the button and fish a new one through?
2. If it's not the wire, what else could it be? Are there bearings or sleeves in the steering column that could wear away and complete a ground with the horn button?

Thanks!
