A/C Not as Cold While Driving
Hi,
I did a lot of searching and my exact case seems to be different than what I've found on other threads. I have a 2001 Coupe with the Dual Zone Climate Control. I just had my compressor, drier, and orifice tube replaced. I could hear the actuator move when I re-indexed the actuator which I've done with the fuse and the DIC (by clearing HVAC codes of which there are none). My driver's side A/C is warmer than my passenger's side and the problem (as stated in the title) is exacerbated when I am moving. Can anyone shed some light?

You might check with who did your AC and make sure they flushed your system. I had my orifice tube plug up after a guy did my AC work. Took is someplace else, they flushed it , replaced the tube, and is working fine. It could also be a broked gear in the actuator.

Thanks! We have discussed doing an evacuation and recovery of Freon. It appears the high pressure is too high and the low pressure is too low which could indicate a clogged orifice tube. He said if my system was really dirty, then it will clog a brand new tube. Does this make it less likely that's an actuator issue? He also thought there could be debris on my condenser.
It sounds like if we go through the filter changing procedure and recharge the system properly, it could fix it.
Sound good to everyone?

Myself included, I consult a 10 year GM service tech that has the proper guages and experience to help me the C5/6's requiring cooler cabins
Fighter jets magically expand hot air to make cool cabin air, I call my GM tech buddy
the vacuum lines under battery posted above is VERY valid info and always good to inspect, any HVAC codes for the actuators?
And of course, as your A/C tech has discovered, having the correct pressure is a good starting point

Air in the system will also cause high discharge pressure, since air is a noncondensible contaminant in the system. A total evacuation of the system will eliminate this possibility as well.
It sounds like you're on the right track.

Wow, guys, thanks for getting back to me so fast.
Steve, I can relate to the fighter jet comment as I studied Aeronautical Engineering at USAFA. I would say it's very easy for a fighter jet to pressurize the air because air is compressible at 300 ft/sec.
Quicksilver, I will visit my tech in the next few days.
