I know the horn works because when I place screwdriver between the screws holding the inverted cup and plastic ring and the side of the inverted cup the horn blows. But the horn does not blow when the horn button is depressed. The horn will also blow while I am trying to install the horn button but stops when it bottoms out against the steerng wheel. Is there a spring or spacer between the horn button and steering wheel? I have been unable to locate pictures or litature assocated with the horn button assembly. Any help would be greatly appreciated. Thanks Redo
