The A/C in my 95 Saturn SC2 is not blowing cold. The compressor kicks in, but the pressures are:
Static (Engine off): 53 High 51 Low
Dynamic (Idle at 750 RPM): 62 High 46 Low
These readings are at an ambient temp of about 62F
Is there any way of pinpointing whether this is a bad compressor or expansion valve? Should I just have the system evacuated and replace both? Try adding a little R134a and retest?
