said by Xstar_Lumini:The door cannot be stuck otherwise no air flow would come out, but how can it be low refrigerant when the other 2 vents throw cold air? Wouldn't they throw wsrm air too?
the right side vents pull the air from the right side of the coil, left side vents from the left side. its common occurance, the W body forums are full of info on this.
before you start digging and looking at vent doors and the like get an AC shop to put his guages on it to see if the pressure is right.
