AC is too cold!!!

Seriously, bad kick out switch. Charge 134A recovered was very close to spec. This was during the FI cleaning. Fan on speed 5, rec, idle at 1200 RPM. The over driven aggressive engine fan is useful out here. 85 degrees out and 3/4 the way into the garage with no helper fans.

Looked at ice on AC lines and knew why it always dumped water when I started it the next day. The evaporator ice would melt and fan the next day would blow it out the drain...

Whats wrong with 42 degrees? Mine will drop right down to about 35 before it kicks out which is where it should drop down to.

Icing up the evaporator and AC lines. Turns the evaporator into an ice brick. Was going below 32 degrees before kicking out from evaporator pressure reading temp conversion. Temp in pic above is measured at center seat.

Seriously running around with AC on speed 1 or 2 I'd have to add some heat - it was too cold...

Does this have a variable displacement compressor?

 

[THEFERMANATOR]

Put a set of guages on it, but it should kick the compressor off around 18-22 PSI. As far as I know the later DELCO's are still a fixed displacement design. I'm using the low pressure switch from an 01 DURAMAX truck on mine, and it will kick off right around 33-35 degrees. A slight overcharge of oil or refrigerant will cause icing o occur in a low pressure cutout system. Mine also will drain out water later on, but it doesn't ice over.
