RELAY AND FUSE HAVE BEEN SUBSTITUTED AND THEY WERE GOOD. HORN WIRE IS ON.

When you depress the horn button on the steering wheel you should hear the relay click. If so then the horn is bad or it has a bad ground.
If you remove the horn and connect directly to 12V and it works, then the horn is not grounded properly.
It grounds to the chassis.
