My 2010 Ford Edge horn quit working fuse is good
unplug the horn then get a test light and ground it somewhere and touch it to one of the terminals while someone else pushes the horn button. if no light go to the other terminal on the wires and do the same thing. if you get a light on one of the terminals chances are the horn itself is bad. if no light then you need to check the wires for breaks or have the horn relay checked.
