Horn does not work

Welcome to 2CarPros.

I'm a bit confused. Do you need the location of the fuse or have you already replaced it? You mention both in your question.

Now, if the fuse was replaced, we need to check if there is power to the horn itself. It could be bad. Using a test light, have a helper press the horn button while you check for power at the horn wire and see if the light comes on.

Here are a few links that may help. I am also adding how to check a fuse because I need you to check if there is power in the fuse box to that circuit and it's discussed in the link.

Start with this and let me know the results.
