Horn stuck on when pressed?

For some reason, it seems most of my vehicles (purchased used) have horn problems. My F350 is no exception.

The horn hasn't worked since we bought the truck. I checked the fuse and it was missing. After adding a fuse, the horn will work, but will stay on. It's not a problem in the wheel, as you can clearly feel it's not stuck.... so, what else could it be? I'd really feel better being able to use a horn!

The horn relay is built into the Central Junction Box and is controlled by either the horn button on the steering wheel or the VSM (vehicle security module).

Here is the pinpoint tests from AllData:

Try this.....take the airbag off.....remove the front cover with the ford emblem....beneath that is a brown/copper looking "sheet" this is the switch that was pushed too hard and then stuck, pop it back out....put everything back together and check it it should work.

Nice tip! Sounds exactly like what in need to do. My little Ford emblem is dented in, st that is probably what is causing it. Thanks!!
