I bought a 2014 Ltz about two months ago with 67k on the clock. Is there a way to tell if the condenser has been replaced(different bracket, color, shape, anything)? I bought it in a Minnesota winter so I couldn’t test to see if the ac worked or not, and reading this whole subject is worrying me. I have already had to replace the oil pump, if I gotta do ac parts too, I may just drive it off a bridge.
