A/C issue!!! Please help
I've recently purchased a 1976 Cadillac Coupe Deville. I noticed that the previous owner took the vehicle to a mechanic that really had no idea on what they were doing with this vehicle. I've been able to correct 90% of the issues. My final issue is the A/C. Since no one carries or sells R12 anymore, I've been forced to do the R134 conversion. Everything has been successful for the most part but now the A/C will not blow cold anymore regardless of what setting it is on. The switch tested fine, the pressures are good. I'm leaning more towards a vacuum issue. I did noticed that the heater control valve has no vacuum to it and i'm curious to know if this may be an issue. I did notice as well that this was a "California emissions vehicle." Would anyone know how to get a hold of a vacuum diagram so i may troubleshoot? Thank you!!! Any advice or help is appreciated.
