What could be the cause of my A/C blowing hot heated air on the drivers side & cool, A/C air on the passenger side?

Asked by Jun 05, 2013 at 12:06 PM about the 2002 Land Rover Range Rover 4.6 HSE

Question type: Maintenance & Repair

My A/C blows hot, heated air on the drivers side & cool, A/C air on the passenger side. It
also blows the same way for the rear A/C. How could I fix this problem myself? Is it the
blend doors, how do I get to them? It has R134A. The low side port tube runs cold, the
high side is hot, is this normal? Any help would be greatly appreciated.

No idea how to put the HVAC system in diagnostic mode for the L322 Range Rover, for Discovery II it's simply holding the distribution and auto button while switching the ignition from off to on. It then displays any error code after a short self diagnostic check. The L322 might have the same system but I am not sure.
