Proper charge level? What was your method of determining proper charge level? Proper type and amount of oil in system?
Why was new compressor installed? Was system flushed of any debris and receiver/dryer and condenser replaced if old compressor failed?
Expansion valve needs to be replaced?
Blend actuator/door working properly? Force a system calibration and see if any codes come up (MTC or ATC?).
If you donít understand some of my questions, ask, and will explain further.
