Question...while mounting a Stebel horn on an '08 3 behind the grill, I slipped while trimming the plastic for the mount and perfed whatever the A/C component is (looks like a radiator, mounted in front of the radiator). I know, big "slip", but the system discharged the 134a; need to know what part it is, how involved the replacement is, and what kind of financial damage did I do to the poor car in the name of a new horn? I have a Mazda shop around here that does the work...just don't want a lot of sticker shock walking in.

Good thing its winter!

 

what were you trimming it with? a chainsaw?
