An HVAC system is provided and includes an evaporator for providing cold air and a heater core for providing hot air. A heater airflow path directs an airflow through a heater air outlet where a heater damper door controls the volume of the airflow through the heater air outlet. A defroster airflow path directs an airflow through a defroster air outlet and a defroster damper door controls the volume of the airflow through the defroster air outlet. The defroster damper door operates independently from the heater damper door. A separation channel is located between the heater airflow path and the defroster airflow path to separate the airflow of the heater airflow path from the airflow of the defroster airflow path.

1. An HVAC system for an automotive vehicle comprising: an evaporator for providing cold air;a heater core for providing hot air;a heater airflow path to direct an airflow through a heater air outlet;a heater damper door to control a volume of the airflow through the heater air outlet;a defroster airflow path to direct an airflow through a defroster air outlet;a defroster damper door to control a volume of the airflow through the defroster air outlet;a separation channel that is disposed downstream from the heater core, forms part of the heater airflow path by communicating airflow to the heater air outlet, and crosses the defroster airflow path, wherein the separation channel prevents the airflow of the heater airflow path from mixing with the airflow of the defroster airflow path at a position at which the separation channel is located;a bypass door disposed downstream from the heater core and upstream from the defroster damper door at an entrance of the defroster airflow path, the bypass door controls a volume of hot air that flows from the heater core directly into the defroster airflow path so as to control a temperature of the airflow through the defroster air outlet without disrupting a temperature of the airflow through the heater core and in the heater airflow path; anda mixing chamber, wherein hot air from the heater core flows into the mixing chamber independent of a position of the bypass door, wherein the cold air from the evaporator and the hot air from the heater core form mixed air in the mixing chamber, and wherein the hot aft controlled by the bypass door flows directly from the heater core into the defroster airflow path and bypasses the mixing chamber so as to pass through into defroster airflow path without mixing with the cold aft from the evaporator,wherein the defroster damper door is configured to operate independently from the heater damper door. 2. The HVAC system of claim 1, further comprising an air mixing door disposed upstream from the heater core and near an entrance of the heater airflow path, wherein the air mixing door controls an amount of cold air that flows from the evaporator to the heater core. 3. The HVAC system of claim 1, further comprising a vent air outlet and a vent damper door to control a volume of the airflow through the vent air outlet, wherein operation of both the heater damper door and the vent damper door together control a ratio of airflow volume through the heater air outlet and the vent air outlet. 4. The HVAC system of claim 1, further comprising a first actuator configured to control the operation of the bypass door, and a second actuator configured to control the operation of the defroster damper door, wherein the first actuator is configured to operate independently of the second actuator. 5. The HVAC system of claim 1 further comprising an actuator to simultaneously control the operation of the bypass door and the operation of the defroster damper door. 6. The HVAC system of claim 1, wherein the heater damper door movable between a full open position, at which the heater air outlet is maximally opened, and a full closed position, at which the heater air outlet is fully closed so as to prevent airflow from passing through the heater air outlet, and the defroster damper door movable between a full open position, at which the defroster air outlet is maximally opened, and a full closed position, at which the defroster air outlet is fully closed so as to prevent airflow from passing through the defroster air outlet. 7. The HVAC system of claim 3, wherein the heater damper door movable between a full open position, at which the heater air outlet is maximally opened, and a full closed position, at which the heater air outlet is fully closed so as to prevent airflow from passing through the heater air outlet,the defroster damper door movable between a full open position, at which the defroster air outlet is maximally opened, and a full closed position, at which the defroster air outlet is fully closed so as to prevent airflow from passing through the defroster air outlet, andthe vent damper door movable between a full open position, at which the vent air out et is maximally opened, and a full closed position, at which the vent air outlet is fully closed so as to prevent airflow from passing through the vent air outlet. 8. The HVAC system of claim 1, wherein the bypass door is movable relative to the entrance to the defroster airflow path between a full open position, at which a maximum volume of hot air flows directly into the defroster airflow path and the temperature of the airflow through the defroster air outlet is a maximum temperature, and a full closed position, at which a minimum volume of hot air flows directly into the defroster airflow path and the temperature of the airflow through the defroster air outlet is a minimum temperature.
