I would also suggest you consult the following: https://rivperformance.editboard.com/t4721-faq-horn-problems. I think this is a wealth of knowledge about various horn issues, beyond the backside of the airbag and the point where sounding the horn starts, mainly your hand on the center. Could be a relay, could be a fuze, but when a fuze blows for no good reason, there is usually 'A' good reason it blew in the first place which requires your Sherlock Holmes hat, a PowerProbe, a multimeter, a troubleshooting light or continuity tester and diagrams and lots of patience, unless the problem becomes obvious like a broken wire or a burned wire or a corroded wire. Fun if you have the time, but annoying if you, like 90% of the population here aren't retired. I pulled apart my steering column and did find the white disc with a metal ring on the back coated in some grease, and I wiped it down. I'll be heading out to work on the '98 today and see if the horn sounds. With a 24 year old car, it's always something. I have to learn how to post pictures here.
