    2008 -: AC works great and blows cool. After a while the coolant line near the compressor appears tofreeze up and no longer blows cool. Refrigerant level looks good. Also just replaced the thermistor. Anything else I should check?

    The outdoor ambient temp sensor (thermistor) in front of the radiator.
