If the AC is turning on but is just not getting as cold as it should then you more than likely have low refrigerant in the system. When the refrigerant level gets low the compressor will not run long enough and will not achieve the needed pressures to allow the system to get cold. I would typically install a pressure gauge set to see if it is low. If the system is full and it is doing this then I would suspect a bad metering valve or a control system issue. If you are going to have the vehicle looked at, consider using YourMechanic, as a certified mechanic can come to your home or office to diagnose your AC system and make the repairs needed.
