The vehicle may be low on refrigerant, due to a condenser, or compressor leak. If the vehicle blows ice cold one minute, then warm until the vehicle or AC is shut off, then you may have a malfunctioning expansion valve. Another possibility is malfunctioning controls. I recommend having a mechanic, such as one from YourMechanic, run an inspection on your AC system, and recommend the best path to repair.
