All - thanks in advance for the help.

I have a 2000 Malibu and can't seem to find much on this problem. Basically the AC doesn't blow cold.

I picked up a new gauge today from O'reillys. When I attach the gauge and fire everything up, it gives me a reading of about 50 psi. I turn on the AC and the compressor seems to be cycling, but nothing cold is blowing out of the dash.

I had the problem last year where the AC switch on the dash wouldn't stay on, which seems to be a big problem. So, I took apart that switch and cleaned everything and put it back together. The AC will stay on now, but the recirc is a little intermittent.

Any ideas on what to tackle next? I don't have much experience with AC units, and no real access to the higher end tools.
