The switch housing vibrated the screws out while riding, I guess I didn't tighten them good enough when changing bars. I taped it together with black tape about 10 minutes later. Now the horn doesn't work. It still has the spring since it pops back to where it is susposed to be when you press it and let go. Is there something inside that could have fallen out or is something just out of place?

 

Sounds like it's not grounded
