ABSTRACT:
A method of air conditioning system temperature control for a motor vehicle is disclosed. The method includes the steps of measuring an air conditioning compressor discharge pressure and determining if the discharge pressure is greater than a predetermined maximum pressure. The method also includes the step of beginning a forced recirculated air mode if the discharge pressure is greater than the predetermined maximum pressure. The method further includes the steps of determining if the air conditioning system is already in a forced recirculated air mode if the discharge pressure is less than the predetermined maximum pressure, and determining if the discharge pressure is less than a predetermined acceptable pressure if the air conditioning system is already in a forced recirculated air mode. The method still further includes the step of beginning an outside air mode if the discharge pressure is less than the predetermined acceptable pressure.
