horn does not blow?

Hello,

The horn can be inoperative due to a bad relay, faulty wiring or defective horn.
First check the relay for the horn.
It is located under the hood power distribution box (relay box). I have attached the diagram of the location for that relay.
Check 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 connector. Check the ground. Make sure it is not corroded or loose.

If the wiring is good and you have power to the connector, then it is likely a bad horn.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
