Abstract
An HVAC system for a vehicle includes a housing, a front HVAC unit housed in the housing and having a front blower, a first airflow path, and a front air mix door, a rear HVAC unit housed in the housing and having a rear blower, a second airflow path, and a rear air mix door. The HVAC system further includes an evaporator having a first portion disposed in the first airflow path and a second portion disposed in the second airflow path, and a heating core having a first portion disposed in the first airflow path and a second portion disposed in the second airflow path. An airflow directional door is disposed between the first airflow path and the second airflow path to regulate airflow from the rear blower to the first airflow path.
