SOURCE: ac vent problem

Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.

That is correct, the air blend door actuator. "flapper valve" may need to be replaced or cleaned and free from binding up. Good luck and hope this helps. If there is an Auto Zone in your area, they can order the part you need and give you the step by step instructions to removing the old actuator and replacing it if it's damaged. Good luck and keep me posted, be glad to help.

SOURCE: Air conditioning only work on passenger side of car.

It is a door actuator motor that is not working and the dash will have to be removed to access this motor

Either your refrigerant needs to be recharged or the pressure switch is bad, I would have the system charged correctly first.

2001Chevy tohoe Cold air blowing threw back vents but not front vents?

When AC on and cold air from rear but not front is usually a blend door/heater box issue. You may have a non functioning blend door motor that controls hot/cold distribution of airflow

Why does My thermostat Not switch between ac,heat,defrost . there's cold air coming out of vents but not cold enough to be ac. Initially when this started the ac was blowing hot air

If the air flow cannot be controlled from vent/defrost/floor you may have a blend door issue. This is an electric motor that operates a door in the heating system to control airflow. There are usually 3 motors controlling airflow direction,heat and recirculation. The Ac not blowing cold may also be another problem. If the AC is operational, the compressor will be engaged and the Ac low pressure line under the hood will bw cold. If this is all ok then a blend door issue should be suspected

2002 Taurus ac comes on and is cold but doesn't come threw vents!

the most likely problem would be a blockage in the ducting from the blower motor to the vents, the blower motor is malfunctioning or the valve that changes where the air goes is stuck sending the air somewhere else.

2004 ford expolorer air conditioning will not stay on

I would suspect the AC compressor cycling switch (located in low pressure line from compressor) or a AC cutoff wide open throttle relay ( in under hood fuse and relay center) would be causing this problem.

My A/C used to blow out very cold and with lots of force at the vents, now I get cold air but you can barley feel the air coming out of the vents. The fan sound like it is on high but very little airflow....

It sounds like you have a blend door issue.Try cycling the air to blow on different parts of the cab ie: defrost,to floor to vent.if you have cold air blowing good on all selections and you know your motor is working on all speeds,then you have a blend door not opening.The control for that is behind the heater/ac control unit.They do go bad from time to time.You can pick up a replacement at either a dealer or a Auto Parts place that sells GM or AC DELCO parts.

Cold AC but weak Airflow---Also Driver side not as cold as passenger

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