i believe the air reply is the air blowing out of the vents and yes the air blows fine on all control numbers and vents just after 20 minutes is blows warm and the compressor shuts down !!! when vehicle cools off it will be ok for another 20 minutes and does the same thing compressor shuts off !! keeps blowing just warm air !!!!!!!!!!
