First thing to do is remove the wire from the horn and connect it to a meter or test light. If pressing the horn pad sends power out the wire then the horns are bad. If not then most likely the horn pad or clockspring is the problem.

The horn on my 2015 stopped working, and I traced it down to the ground wire. The horns were getting power when the button was pressed, but without the ground, nothing happened. I did have to remove the grill, and I added a splice and a jumper on the ground wire & just added a lug connected to the frame nearby.
