Abstract: An HVAC system for a vehicle including: a transparent metallic layer configured to be mounted to a windshield; a control module configured to apply voltage from a power supply to the transparent metallic layer to heat the windshield; and an HVAC case defining a face outlet and a combined foot and side window outlet, the HVAC case including a mode door movable to control airflow through both the face outlet and the combined foot and side window outlet.

Abstract: An HVAC system including an evaporator, a condenser, an expansion valve, and a compressor. An HVAC case includes a first heat exchanger having a first height, a second heat exchanger having a second height that is greater than the first height, and an air mix door movable to direct airflow from the second heat exchanger to the first heat exchanger or around the first heat exchanger. In a maximum hot mode, a valve system directs the coolant through the condenser, the first heat exchanger, and the second heat exchanger, and the air mix door directs airflow from the second heat exchanger to the first heat exchanger. In a maximum cold mode, the valve system directs the coolant through the evaporator, the first heat exchanger, and the second heat exchanger.

Abstract: A secondary loop HVAC system including an evaporator, a condenser, an expansion valve, and a compressor. A refrigerant loop is in fluid communication with each of the evaporator, the condenser, and the expansion valve. An HVAC case includes a first heat exchanger and a second heat exchanger. A first coolant loop is in fluid communication with the first heat exchanger, the second heat exchanger, and either the evaporator or the condenser. A valve system is configured to control flow of the coolant through the first coolant loop. In a maximum hot heating mode, the valve system is configured to direct the coolant through the condenser, the first heat exchanger, and the second heat exchanger. In a maximum cold cooling mode, the valve system is configured to direct the coolant through the evaporator, the first heat exchanger, and the second heat exchanger.

Abstract: The present teachings provide for a door linkage system including a drive side and a driven side. The drive side includes a drive gear and a drive arm. The driven side includes a driven gear configured to mesh with the drive gear and a guide plate in cooperation with the drive arm. The drive side moves the driven side between an open position and a closed position. Proximate to the open and the closed positions, the drive arm moves the driven side. Between the open and the closed positions, the drive gear moves the driven side.
