Thank you for watching.
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.
good video just curious do you always use wheel chalks to start your truck or did you do that for your youtube channel

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