Does the relay make a click sound when you push the horn button?
Try running a jumper wire from the horn ground wire (at steering wheel) to a good ground. There should be a wire at the rag joint grounding the column to the steering box. Often this is forgotten when repairs are done, and the horn loses it's ground.
Let us know what you find.

A rag joint is part of your steering shaft,(where it comes out of the firewall) should be right before the steering box,two bolts a rubber disk shaped thing. I dont think it has anything to do with your horn working or not working though. Im not sure about the wire your looking for.

one more thing to check, is if the horn is getting a good ground, pull it, wire brush it, then reinstall.....if the relay is clicking and power is coming to the horn, there aint much else that i can think of, let us know

I changed my radiator support(that the horns mount to) and had a ground issue with my horns. has your horn ever worked? Try running a wire from the mount screw for your horn to the frame or maybe the neg on your battery if the horn works then make sure your radiator support is grounded.

Try having someone tap on the horn when you push the horn button if it honks you may have a pitch adjusting screw on the back of the horn you can adjust this screw a touch it may or may not be sealed with silicone or it might not be adjustable. Either way if you have power(12volts) at the horn it has to be a poor ground or faulty horn.

That gives us enough infortmation to solve the problem
The problem is in your steering coloum I don't know the exact configuration of you coloum but I will tell you this there should be a wire coming out of the coloum that goes to the horn relay the other end of the wire goes into the coloum and should be attached to a spring loaded carbon brush holder the brush rides on a brass ring wrapped around the inside of the steering coloum. The problem is the carbon brush is worn out or the horn button is faulty, either way you are going to have to check for continuity from the horn button to the wire coming out of the base of the steering coloum. Always check all wirering under load (with voltage going through it) as continuity can be read with even just one tiny strand of wire load test will not lie if there is no voltage you know the circuit is no good even if you read continuity.
Good luck.
