QUESTION: If there is a leak in the system should it not affect all air vents? this van has separate digital climate control for passenger, driver and rear seats, only the front driver side is not as cold, both passenger and rear vents blow cold air.

Answer
the air flow goes thought the heater core first then the evap and if there is no enough freon to remove the heat from the air  the pass side is the last vent that gets the cold air so it feels warmer or hot even.Like I said  i live in Atlanta and if u need this looked at for where it is  I do this sorta work on the side.
