I am sure that most of you with one of these trucks knows the stock heat/air blower motor on these trucks does not move a lot of air. Does anyone know if there is a different number blower motor and squirrel cage fan with a higher CFM rating that could be installed in the factory location on this truck to increase the air flow in the stock heat/air system?
