I have been having horn problems for two years it has low rpm,s and sometimes didn't work at all,two years ago sent it for testing and fixing got it back same problem last fall sent it to what was supposed to be the best horn shop around got it back during winter took it into the shop and tried it directly on battery worked good high rpm,s good and loud. Today put it it car same old problem if I run a jumper from battery to horn works great but not when using wiring harness, got six volts at switch terminals and at wiring terminals, took switch button off and tried crossing there with test lead same problem, it must be wiring harness? It all looks good and I'm crossing a terminal at switch that reads six volts with meter can't figure this out

Bad ground ???

You don't have a horn problem. You have a wiring problem. Somewhere there likely is a loose connection which gets hot and will not carry current. Just because 6V shows up on a wire doesn't mean it is capable of carrying current when under load. Fix the wiring.

I figured it out when I was using a test lead and closing the circuit I only had the button removed wires were still hooked to back section of switch I removed wires totally from switch and touched them together and it works great need new switch

You can repair your old switch, better than the reproduction steering column switch IMO.
