Abstract
A system according to the present disclosure includes a start-stop module, a bypass valve control module, and a flapper valve control module. The start-stop module is configured to stop an engine of a vehicle independent of an ignition system of the vehicle. The bypass valve control module is configured to adjust a bypass valve to a bypass position to prevent engine coolant from flowing from the engine to a heater core of the vehicle when the engine is stopped independent of the ignition system. The flapper valve control module is configured to control a flapper valve to adjust an amount of airflow from an evaporator of the vehicle to a cabin of the vehicle through the heater core.
