I have a 2007 chrysler 300 touring with the single zone hvac control. I have put a new evaporator in ( it was leaking) a new compressor, and a new drier from four seasons on rock auto. I also replace the expansion valve with a denso. Now the problem I am having I believe I had before replacing these components but when at idle on fresh air and max fan I have high suction pressure and slightly low high pressure. 49 psi low and 165 high. I get around 58 degrees out of center vent. when I rev it up pressures and temps get better. i thought maybe the aftermarket ac compressor was not making enough flow or maybe I could try adjusting the expansion valve. It is properly charged. Condenser is not blocking and fan motor operates fine.

 

I am confident all blend doors are operating properly. i even pinched off heater core lines and had no change in temperature from center air vent.
