hey guys i've noticed my horn doesnt work..i've found the problem.in the gap between the steering wheel and the column i could see a brass ring and a piston type contact..when i shorted them the horn went of..the problem is.. the piston is shot or the steering wheel contact is bent..it works at like 12 o clock .. thats it..will this ring come off with the steering wheel.?? will autozone have a new piston...???
