Broken horn
 

I'm almost embarrassed to ask this, but...

I replaced a fan motor in my '94 touring, which meant that I took half the engine bay apart to get to it. Everything is great now, except my horn doesn't work. I put in a new horn relay and checked all the visible wiring and can't figure out what went wrong. I also can't figure out if there's a fuse to check.

Any tips would be great.
