[QUOTE="Tourmax, post: 205436, member: 5304"] Well, chucked a can of refrigerant in the Vette and the AC now runs normally. Well, it's pumping and not short cycling that is. The performance at the vents varies between very poor and not cooling at all. Well, that's contamination in the refrigerant. Obviously, I didn't pull it down far/long enough to clear the air and H2O hanging around inside the system. I hooked up my cheapy vac pump and........nothing. Crap, The pump packed 'er in on me. That also may explain why it didn't evacuate the system (IE: completely) last time I used it. So I popped a couple bucks on a new pump and gauge set: [IMG]https://i.ebayimg.com/images/g/T5kAAOSwVWpa9Md4/s-l1600.jpg[/IMG] Not high end by any stretch of the imagination, but it will work fine for the few times I need to bother with vehicle AC systems. It's also shipping out of Ontario (not China, although it is a "made in china" thing), so it has a half decent chance of showing up on time. If it's coming out of china these days, you're lucky if it shows up at all...... [/QUOTE]
