Year: 1969
Make: Chevy
Model: C20
Engine Size: 350/5.7
Refrigerant Type: R12
Country of Origin: United States

I have a 69 Chevy C20 w/factory AC. The AC, heater and defroster all do not work. The most I get is noise from the fan. It looks like all the factory parts are there. but the compressor is shot (bearing noise). My question is am I better off repairing the factory system to R12, repairing/converting the factory system to R134a or replacing the factory system w/Vintage Air Sure Fit system? I know what the Vintage system will cost me. What will I likely spend and get in performance from a factory equipment? Thanks for your opinions.

Personally I would repair and upgrade the original system.

My vote is to keep it stock/R12. All the parts are still avalible, compressor and condenser can be upgraded to make it work even better. But the cab in a truck is really not that big so I'm not sure upgrades for cooling purposes is even worth it unless you are replacing the part anyway.

I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!
