Hello,
An inoperative horn can be due to a faulty horn relay, wiring issue, malfunctioning switch or a bad horn.
The relay for the horn is located in the under-hood fuse box (see diagram below).
Check the relay for any burn pin(s) or corrosion.
That relay can also be tested:

If the relay is good, then check to see if you have any power to the horn. If there is power, then the issue is faulty horn. If there is no power, then it could be a bad switch.
I have attached the wiring schematics below for your reference.
Please let me know if you have any questions.
Thank you.
