horn stopped working

Hi,
I have a 97 Ford Taurus, and my horn just stopped working the other day. I replaced the battery a couple months ago. I was wondering if this could be a fuse, I looked at the fuse box last night and didnt see anything for the horn. Any feedback or assistance would be greatly appreciated.....

Thank you

My Haynes manual says that there is a horn fuse, it just does not say where. I would look in the engine compartment as well as the passenger compartment for one labeled as such.
