So, when I got my Camaro my horn sounded like a dying frog, but luckily when I was taking my wheel apart to replace the ignition cylinder I accidentally broke the plastic part that made the horn work at all! Any suggestions about what I can do to fix this situation?

 

Replace it - horns are cheap, and on the shelf at any auto parts store.

 

If you're talking about the round thing with the copper track on it you can find one at most any part store. If you mean the plastic buttons that you push to operate the horn, several vendors on here sell them new for $20-$25 or so

 

I must be getting senile! Read about a "wheel" and assumed a tire wheel, not steering wheel! What a dumba$$! I gotta wake up!

Horn buttons available on ebay all the time, or Hawks or Thirdgen Ranch.
