Compressor, evaporator, and expansion valve. Dryer, replaced. Also, the sensor on the evaporator was replaced. No cold air. The clutch engages. None of the lines feel cold.

Hi,

If the compressor clutch engages, I need to know what the high and low side pressures are. By chance, do you know what they are with the system running? Also, what is the outside temperature when you check pressures?

Also, how much Freon and how much pag was added?

Let me know. Also, this link may be of interest. Take a look through it in the interim.

Let me know.

Take care,

Joe
