Horn Stopped Working

[Jttama]

I noticed the other day that when I set my alarm I didn't hear my horn. Then I pressed the horn and it wasn't working. I checked the fuse that's located in the interior passenger compartment and it was fine.
I don't see a relay in the owner's manual. Any suggestions???

It help to know what year the expy is and is important to know how you checked the fuse

Check and clean the horn contacts for a snug fit.

@Bedrck47 It is a 2007 Ford Expedition Limited. I tested the fuse by removing it and testing it for continuity.
@docraymund I plan on checking the contacts this morning. Thanks for the input.

Well...It was the obvious. The horn was disconnected. I don't see how that could easily happen so now I'm wondering if someone deliberately disconnected it.
