I have an 05 LR3, 4.4 dual climate controls. Craziest thing I've ever seen, if I put the passenger control to hot and the drivers to cold, I get hot air on the drivers side. Swap them, get cold on drivers and hot on passenger. Both controls on cold, hot on driver, cold on passenger. Both controls on hot, cold on driver, hot on passenger. Occasionally I can get cool air on the driver and ice cold on the passenger with both controls on cold, but not very often. Ideas?
