I've got a 2008 jku rubicon, my horn quit working recently and the abs system started acting up. I took it in to the dealer to replace the clock spring under warranty. This fixed the abs issue, but I still have no horn. The horn does not work when using the panic button either. The horns are new Hellas from amazon and are wired to an additional relay. Just getting no signal from the factory horn wiring. Where should I start? Any ideas?

Check the horn mounting bracket ground to the body is where I would start.
