I spent about 1600 bucks getting a new compressor and lines put on my car. Its been updated to the R134a instead of the old R12. Its got a fan from a W140, which is like 11" compared to my old 8" fan. My A/C should be blowing cold but all it does is suck down my gas and give me nothing in return. I can turn on my fan and it blows at about the same temperature, I can't even notice a real difference.

I'd like to get this fixed before I have to drive back down to Louisiana and suffer through the heat. Any ideas guys?
