Horn not working cant find fuse

It's under the hood. when you depress the horn button that switch energizes a relay that in turn operates the horn, which needs more current than could be switched through the horn button. the relay and the fuse (it's a 20 amp fuse if my chart is right) are both in the underhood fuse box which should be on a fender, maybe near the firewall. you will have to open the box to see what you are after but there are only a few things in it. hope that helps.

The horn fuse is in the under hood fuse box. It is a 20 amp fuse. Good Luck
