I get very little cold air out of the vents even when the temp is set to 60 degrees and the a/c is on. Also the very little cool air I do get seems to be coming out of the passenger side vents. The sight glass for the a/c line is very white and cloudy. I was told with the r-134a that this was normal but I am starting to wonder if I have a leak in the system somewhere. Is the sight glass suppose to be cloudy, with the old freon systems I think that meant a low freon condition???????
