Fan is perfect, both condenser and cabin. Air is not cool. You have to run on a highway at high rpm to notice any cooling. My question is what causes the low side pressure to be 85 psi at idle instead of 40psi??? Darrel

Hi, thank you, the fan is blowing, air cool at high rpm, warm at idle. Compressor kick in but high pressure side is approx. 250 psi and low pressure is 85 psi. Is there a valve that controls which evaporator gets the most refrigerant? Does it sound that the valves in the compressor are flapped...
