Thanks for the replies.

Still a couple of questions. Is it normal for there to still be a few bubbles in the sight glass? The air seems to be cold coming out the vent, but again, the temp was only in the 80's (very rare for charlotte in july but welcome). I took the car to get the A/C charged to a shop that I have never used before. I'm just trying to determine if they did a good job of charging the A/C. By the way, is there a way I could buy some r-12 from someone so that I don't have to pay 60$ a can to get my a/c charged? I read in one thread prices in the 15 range. I realize I can't by it direct from a dealer, but maybe some of the guys on the forum would sell it.

And, if the switch is bad can it be replaced without losing coolant?

What really seems odd to me is that someone would design a car where the high speed fans come on when the gauge temp reaches 100C (while the car is sitting still in my garage), but the low speed fans won't come on when the A/C is running so that the temp won't get to the point where the high speed fans need to come on in the first place. Maybe I'm the only one that finds that design very strange.

I've always had japanese cars in the past and the engine temps seem to stay steady at one temp. It just bugs me to see the guage go up to 107 when it seems to me it doesn't need to. Oh well.

Thanks
