My horn ('53 HJ) sounds without touching it. The car had sat in the driveway for a year, then one morning the horn started blaring, so I pulled the wire from the horn relay. Is the relay bad (it's only about 5 years old)? I hadn't touched the inner working of the steering wheel hub/horn button, so I can't imagine anything is wrong in there. BTW, the rubber gasket on it is new.
