Classic/Antique Car Repair: 1966 Impala Horn, screw driver, quarter moon

Question
I have a 1966 Impala that I cannot get the horn to blow. I've ran a wire directly from the horn to the battery and it blows. So I replaced the horn Relay and it will not blow. Any Ideas?

Answer
Correct me if I'm wrong, but you should have a quarter moon rim inside the steering wheel with a round hub in the middle to activate the horn.

If this is the case, I'm guessing there is a contact problem there. To activate the horn, a metal plate on the hub make contact with another metal plate inside the steering column. Take the horn activator off and check these contacts. You should be able to activate it with a screw driver once the cover is off. If not I suspect a wiring break or loose contact somewhere if the horn wire.

However, most likely the contacts are worn to a point you are not making contact with the activation switch. Cleaning and adjusting the contact points may be all that is needed.

Hope this helps.
