Hello,

When you press the panic button it is designed to blow the horn, till the button is pressed again. It is a standard function part of the anti-theft system.

If the horn does not sound, it could be due to a bad horn relay or a faulty horn.
First check the relay. It is located under the dash fuse panel (see picture below).
Visually inspect for any corrosion or burnt pin(s).
You can also test the relay:

If the relay is good, check to see if you are getting power to the horn. If there is power at the connector then it is likely a bad horn.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
