How do I replace the horn switch on a 2000 gmc sonoma. The horns are good, the fuse is good, the relay is good. The only other thing I can think of is the switch/button. I have never done this on a vehicle with air bags.

There is a safety issue with air-bags. Safety is your responsibility. There is an sir fuse, interior fuse box, unplug it. Wait about 20 seconds. There should be yellow two wire connector, base of steering column, unplug it. You may have to remove lower part of dash. Also, passenger side air-bag, unplug yellow two wire connector behing glove box. Then, it should be safe to work on. You still need to be cautious.
