The horn started to blare by itself. The battery was disconnected and it reset but now it does work. The fuse looks good. What should I check next?

Check the horn button or whatever it has, and check the relay for sticking on (I assume it has one for the horn- I don't have a comprehensive electrical diagram for that system). If the fuse were blown, the horn wouldn't work, no power to it. You may need to find an auto electrical shop or a Chevy specialist.
