Clxon peugeot 207 does not work

Good morning,
I have a Peugeot 207, to which the horn has stopped working, I have checked the fuses and they are fine, my question is, do you have any release that controls the horn?, Where would I be located?
When you press the horn in the fuse box a clac is heard, but even there I have arrived.

Thank you very much for your time.

All the best
