Unhappy Horn does not work on '99 GMC Sierra

The horn does not work on my '99 GMC Sierra. Any clues on how to find out why and/or how to fix it?

Find the horn. Bring power to it from the battery. If it sounds, the problem is in the horn contact in the steering wheel, relay or wiring.

If it is in the column, STOP! Professional service required, as the air bag is involved.

If the horn doesn't sound with direct power, the horn is bad.
