Rear Air Blowing Hot, Front is Cold
2010 S65 is blowing hot air in the rear and cold in the front. Does anyone have a DIY or a fix for this particular car?

Have you checked the refrigerant level?
I’m am not familiar with the refrigerant circuit for these cars. However, if it is a single loop system and low on refrigerant, the available refrigerant will evaporate before it exits the evaporator. If it goes through the front evaporator before the rear and the system is low, the cooling energy will already be used before it goes to the rear.
When my 1999 Corvette is low on refrigerant, the driver side AC will blow warm while the passenger side will be cold.
