Thanks guys, I did the site glass suggestion first, and it is bubbling. I am assuming I am low on freon. I can feel the compressor kick in, and I am getting some cooling, but when its above 75 F, it doesnt work at all. It has been fairly cool the last couple of days, but also humid. Maybe a combination of this and low refr. I will do a pressure test. The guy I bought the car from said it was converted to the new r132, but he didnt change the filter/drier. Would it be a good idea to completely evac, and fill with a new drier?
