Unreliable horn

Have you check all the connections? rusty or dirty connections can give a very erratic behaviour. Also the button spring or contacts may be old. Get an electric diagram and follow all wires looking for defect connections.

Bad Ground is the most common, Then the fuse...........corrosion and such.

Just give them the finger. In all seriousness, get a continuity tester (a light bulb with two wires) and start at the horn button, working you way past each connection until the light doesn't light up.

That's all real good advice, that's what I have done, but don't forget , replacement horns are very low in quality these days. You may have a poorly tuned horn or just a crappy new one. I bought two new horns, one was great the other was very anemic, right out of the box. The path through the steering wheel, down the stem and out down at the end of the steering column is a poor one usually. I did the unforgivable and made my horn button pick a relay then the relay supplies the heavy current to the horn, you shouldn't have to do that but it works.

I too have found aftermarket horns to be of questionable quality. Besides which, Bus horns are not available in the aftermarket at all. So I began rebuilding horns. It's pretty easy after one gets the hang of it and the results are so much better than the aftermarket stuff.
