I do not know if the horn even has a relay in its circuit. The horn sounds when the circuit is grounded which happens when you press the button. Look under the hood and see if the horn(s) are even plugged in. If you can get your hands in there then try running 12V to it and see if makes noise. If it does then check the wiring around it for corrosion and/or breaks in it. I assume you have already checked the fuse for that circuit, which might have more than just the horn on it.

Not giving you a bad time but think about it. If the the button grounds the horn circuit and the horns are bolted to ground then something has to apply power to the horns. There has to be a relay. Unfortunately I don't recall where it is on a tbi truck though.

On the sticky at the top there are some wiring schematics. This was the closest one that I found.

True. Al I can say then is that the relay for it must be in the fuse panel.

Stupid question for an old thread but did you check the switch on the steering wheel? Mine was unplugged.
