This problem is a low freon charge in the system. ...

Thanks.

check the air vent of passenger side for any obstruction and secondly keep your thermostat full towards cold side make sure the ventilator is fully closed position and rotate the air selection knob clockwise and anti clock wise two three times than set it at the required position mainly your air selector seems to be malfunctioning there is nothing wrong with the ac

i have the same problem the acuator under the dash on the right side of the transmission hump controls the left side temp just disconnect it and it will stay on ac and in the winter plug it up put it on heat and disconnect it and it will save u alot of money and time

Possible that the vent is blocked if you meant that the car is not cooling with the AC. If so check the flow of air on the vent , remove and clean the vent.
However if there is heat coming in to the passenger side then the engine room insulation can be open or there is a possible leak from the engine room that allows hot air to flow into the passenger side than the driver side.
I hope this was what you meant, if not clarify once again.

The air doors are controlled by actuators that on of them or so may need replacing.
