Hi,

I have a 2009 Aveo 5 LT, and it is having AC issues.

Problem: With the AC on, the air that comes out of the vents is barely cold, with Recirc (AC Button on, Recirc Button on), and the hot/cold selector all the way to cold (the left).

I have tried refilling the AC system with new coolant, with no resolution. No leaks have been detected.

With AC off:
The low side and high side pressure are normal (70low,70high PSI).
With AC on:
The low side is high (60-70 PSI).
The high side is low (100-120 PSI).

The compressor clutch works normal, and when the AC is on the compressor is running all the time. But, the motor cooling fan is off.

Does anyone have a diagram of the AC system and the electrical AC schematic?

Also, does anyone know if the AC in this car has expansion valve or orifice?

Any help to a resolution is appreciated.
