Dealer says spiral cable, but all steering buttons work except horn

as the title says, we took the 2011 prius into the dealer and they told us it was the clockspring (spiral cable)... the symptom is only the horns to not work, not by pressing the steering wheel or the panic button. every thread i've read about the spiral cable says the panic button still triggers the horns which leads me to believe its not the spiral cable (also all of the other steering wheel buttons work just fine and there are no airbag codes being thrown) the dealers mechanic is just going with the most likely cause and not actually diagnosing this specific car or is it actually the 1k fix of a spiral cable to have a horn on the prius?

 

If you go look at your prius if you have a Gen3, the fuse and relay locations labeled horn on the box map are completely empty... the horn fuse/relay is actually located in a white multi-relay in the fusebox I have tried like hell to get it out but I feel like i'm going to break it everytime I do... I have already tested the two horns via direct wire, nothing is wrong with them.
