no leaks that I can find (UV dye in the freon, checked with a black light), aux fan works fine, condenser fins are clean. Freon flowing past the sight glass is milky looking which I assume is from tiny bubbles in the freon (please correct me if I'm wrong). I just took it for a spin and under way it was blowing about 56 deg. F (ambient is 80). The insulation has fallen off the hard line over the front of the engine... I figure replacing that will buy me a few degrees.
