I seem to recall reading once that the aircon refrigerant contains a lubricant for the compressor, so it could just be running dry.
Not sure though.. Gone 2016 Landmark D4

Does the noise stop when you turn off the AC from the heater control? If it does stop, then a regas with the correct amount of PAG (polyalkylene glycol) lubricant is the first thing to do. If, after the regas, it still makes a noise, then suspect a worn AC compressor.
If the noise does not stop when switching off the AC, then suspect the pulley and/or clutch are faulty and need servicing. Joe
