'06 LR3 dead horn. Suggestions on where to start?

 

Fuse.

 

Funny story, when I first got my LR3 I thought the horn wasn't working. It actually was, but I wasn't pushing it in the right place. I didn't realize there were two vertical horn buttons, one on each side of the steering wheel, instead I was trying to push the center like I've done on every other car I've owned. Accidentally pushed one of the horn buttons while driving later and realized my mistake.
