First "rule," if you have a failure after fixing something, go back and double-check the repair. Without knowing how your air horn is wired, it makes sense something was reconnected wrong. Blowing a fuse is due to high current draw, typically from a short to ground, but also from increased resistance from a device.
Check your repair fist. I'm guessing your air horn operates by a solenoid/valve which opens air to the horn. Could be the solenoid/valve as well.
