Hi everyone. I have a '64 SS that came with factory a/c. It's not working properly. It doesn't blow cold enough air. I'm not trying to compare it to modern day car a/c, but this just isn't working properly. The fan/blower works fine and when you push down the one lever for the a/c, the compressor engages and the engine rpm decreases slightly. I had it to a mechanic who replaced some type of vacuum switch controlling the heat and a/c. He said that the previous owner converted it over to the modern refrigerant and it was full. He seems to think that everything is working properly, but I don't. The air will get slightly cooler but not cold. With winter coming, I certainly don't need the a/c or will even be driving the car much longer. I spoke with the mechanic the other day and told him of my concerns. He is a real decent guy and said to bring it back in the spring and he'll check it some more. I know little to nothing about a/c. I guess there are 3-4 main parts to it. Based on my description, is there something we should be looking at again?? Some thing I can gently pass along to him?? Thank you, Carmine.
