I have a 06 X Type The AC was just repaired (leak in the intake valve) and vacuumed and charged. The passenger side blows much colder then the drivers side. Why? I tried to change the cabin air filter but this did not solve the problem, The car has a Nav system so the climate controls are touch screen. Any ideas?

 

Have this "feature" too. Noticed a few months ago. It's not much colder, but the difference is noticeable. Have not looked into it though.

 

I have the same problem.
I fixed that problem probably 5 times on other cars.
2 reasons for that:
1.left side blend (hot/cold) door broken
2.Left blend door motor broken.
Important question is how accessible the motor.
Motor is sometimes easy to replace sometimes hard.
Blend door is located inside heater core/evaporator housing.
