      @@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.

    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 !

      @@fastrunlogistics3560 el gas refrigerante se revisa con los manómetros, la presión baja debe andar entre 20 y 40, 50 como máximo, y la presión alta debe andar entre 250 y 300, si la presión alta anda en menos de 250 sentirá que enfría poco al estar estacionado y que en marcha enfría más, lo otro que puede estar pasando es que el compresor no esté trabajando al cien por desgaste de uso, así que con los manómetros puestos y el vehículo estacionado acelerelo y vea como se comportan las agujas de los manómetros.

      Sometimes the blower motor plug connection get so hot it get a bad connection. Also the blower maybe bad.
