Here is what I did to track my problem. First power to the horn and it toots. So horn is not bad. So I think it is the relay so I find the relay and supply power to the horn side of relay so wire is not bad from relay to horn. I measure the power coming into the relay, 12 volts, so that is not bad. Ground the ground side of the relay, horn toots so problem is somewhere in ground connection. So I thought the horn switch was bad remove that and the ground the wire coming into the horn switch (just under the steering wheel) no sound. So problem with wire between horn ground and relay. So I look down at bottom of steering column where it enters dash. There is a push together connection. Trace wire from relay back to here. Ground it and horn sounds. So I think the problem is between bottom of column and horn switch. So it has to be a broken wire or bad connection in the column I am just curious as to how much work I am going to get into my trying to pull the column.
