The AC went out on my 2000 Cavalier almost 2 years ago and before it went out I noticed a metal on metal noise every time I turned it on. Once it finally stop blowing cold air I figured I would see if it was low on refrigerant and it was fully charged. So today I finally went and had it checked at Firestone and I was told the compressor, accumulator and condenser needed to be replaced which would be around 2 grand. My question is does it sound like I am being lied to or is it totally possible for all three of these to be bad? Also If I replace the compressor and accumulator and it was the condenser that was bad will it hurt the new stuff I just put in? Thanks in advance
