    On older trucks check your heater coolant lines , if both are hot the shut off valve is defective . The A/C system will not override the heating system . Install manual ball valves on the engine block . Good Video !

    @@bigrigfix what if I’m driving and it’s blowing pretty cold and when I get to a stop light. It starts to blow cool almost warm. Does that mean I’m just low on freon.
