My 98 transport blows outside air from the drivers side vents (even the Left side center vents) and then at the same time blows cold A/C air from the passenger side.
Here are the facts: The A/C switch is on. The interior cabin air filters are clean. The A/C is charged at the correct pressure. From what I can tell all of the vacuum lines are operational out of the cabin air selector switch.
It is like the outside air is being vented on the driver side and the A/C air is going to the passenger side. There is no abrupt explanation for this because it started this by itself. The only thing I can think of it that a piece of debris got into one of the flapper doors going to the driver side.
Is this possible and if so what has to happen in order to fix it?
Any help appreciated.
