horn stopped working

1997 Passport 3.6 2wd. Horn(s) just quit working this week. Does anybody know which circuit it is so I can check the fuse. Anything else I should check?

I do not know the fuse, but if you look at the fuse box under the hood or in the car it might have schematic that tells you where it is. Checking the wires of the horn is good. If you jump it from the battery to the horn you will know if the power side is bad, or the fuse. Ground might be dirty as well.
