There's usually two horns; a high note and a low note. When the horn sounds sick, one of them has failed. Most commonly one will short and cause a fuse to blow, then they'll both be dead. If one horn still works, the fuse isn't blown.
If a fuse has blown and you can't tell which is the low note, you just have to unplug one or both, replace the fuse, then see if the one that's still connected works. If the fuse blows again, the one that's connected is shorted.
Dealers can order the correct horns to insure they will fit into tight places, but they also will usually have universal replacements that are much less expensive. Those will have multiple mounting brackets to fit most applications. You'll probably have to add your own new electrical terminals. Auto parts stores will have the universal horns too.
