I think this A/C System might just might be my undoing. I'll give details on what I know about it. First, as I said, the car is more or less bone stock. The guy I bought it from had the engine rebuilt and put a fairly nasty cam in it. IMHO, this is fine if you're going racing, but this car is worth a bunch of money so it shouldn't be cobbled up. I had that cam taken out and a proper 440 grind put back in. I also replaced what appeared to be an aftermarket heater control valve with an NOS unit (since the old one was frozen anyway). I asked him about the A/C system. In his words, he said he had removed the compressor to have it rebuilt. He couldn't remember who did it. He also said that the system "had been open" but had not been run since he re-installed the compressor and that the drier needed to be replaced. But he seemed very vague about all of it.
After I had the cam replaced, I told my mechanic to refill the system and see what happens. If I have to rebuild parts, I have to do it anyway, right? He checked the system, said that he could find no leaks and that it held a charge. He refilled it with three cans of R134. Said that he wanted to see how it worked before topping off the system. That's what I know to this point. Sounds like I may have to rebuild everything again to make sure it's done properly.
I'm really not as concerned with actual airflow as I am with temperature. Bad airflow is fairly easy to track down. Bringing the temp down is another matter. Very basic question here: What is it that actually makes the air cold? Is it the compressor? Or another part of the system?
Thank you for all your responses thus far...it's a big help.
