    Hello I'd like some insight from others regarding a horn issue with my 2015 prius one. Originally there were many problems: airbag light and traction lights were illuminated on the dash, the aforementioned horn did work if the steering wheel was turned a specific way and would randomly just non stop go off, and lastly the a/c buttons on the steering wheel wouldn't work but the volume buttons did. All that being said today I replaced my clock spring and everything has been solved except the horn. When these issues first occurred I unplugged both horns because I was in a parking lot. Then now that the clock spring has been replaced I connected the horns again. Now they won't work at all. Not when I angle the steering wheel or press the panic button on the key fob. Personally I think it could be the relay, wires, or the horns themselves. I have checked the fuse it's fine. Again I'm open to any new perspectives on this issue. Any help is welcome.
