HVAC calibration procedure?
I have a 2010 Sebring limited hard top convertible. Heat is working fine but turning on the A/C results in ambient air, not cold. This is with automatic temperature control.
System is charged and the compressor is running. A/C lines feel cool.
Is there a recalibration procedure for the HVAC in this car?

Are there any diagnostic codes in the HVAC control module? Placing the HVAC in manual mode and using Appcar, monitor the blend door actuator. Do you see the actuator values changing as you rotate the temp dial?

I did realize that the clutch on the A/C compressor is NOT coming on at all. The system does have a full charge, so I think it's either the clutch or the pressure switch. Not sure what to do next, as you can't just jumper the pressure switch (transducer).
