I have a 69 camaro the problem is the horn does

On most early U.S. cars the horn button only provides a ground for the horn relay , which is located on the firewall under the master cylinder , if you can gain access to the back side of the horn button I would ground the wire to see if your horn honks . If not check for power at the horn relay . I would invest in an assembly manual/ service manual from any of the many camaro restoration companies as it could provide insight on future problems
