Abstract: The present disclosure includes a heating, ventilation, and air conditioning (HVAC) door diagnostic system. The system has a rotatable hard stop lever that contacts, and restricts movement of, both a first airflow control door and a second airflow control door beyond a stop position when both the first airflow control door and the second airflow control door are present and moving in sync. When one of the first and second airflow control doors is not present or the first and second airflow control doors are not in sync, only one of the first and second airflow control doors will: contact the hard stop lever at the stop position, rotate the hard stop lever, and move beyond the stop position. The HVAC door diagnostic system generates a failure notice when the first airflow control door or the second airflow control door moves beyond the stop position.

Abstract: An HVAC system including a defrost manifold. The defrost manifold has a first side window outlet, a second side window outlet, and a windshield outlet. A first rib partially obstructs the first side window outlet. A second rib partially obstructs the second side window outlet. A control door is movable to open and close the defrost manifold. A first wall extends from a first portion of the control door that is opposite to the first side window outlet. A second wall extends from a second portion of the control door that is opposite to the second side window outlet. Movement of the control door varies the position of the first wall relative to the first rib, and varies the position of the second wall relative to the second rib, to control airflow through the first and second side window outlets.

Abstract: A cooling assembly for under a vehicle is provided. The cooling assembly includes a housing, a slab condenser, and a condenser fan. The housing is configured to be attached under and to a floor of the vehicle. The housing includes a top wall, side walls and a bottom wall. The slab condenser is disposed within the housing and horizontally oriented when the housing is attached to the vehicle. The condenser fan assembly is disposed within the housing and directing air vertically through the top wall, the bottom wall and the slab condenser.

Abstract: Disclosed is a vehicle HVAC system that provides for installation, serviceability, or replacement of at least one actuator servo without removal of the HVAC assembly from the vehicle. As due to the tight space limitations, the present invention provides for at least one fastener-less mounting element of the servo assembly to be attached to the HVAC assembly, without the need for additional fasteners which would require additional space to access with a tool.

Abstract: A vehicle heating, ventilation, and air cooling (HVAC) system that includes a module, an evaporator, and a heater core; the module defines a defrost outlet, a side window outlet, a front face outlet, and a front foot outlet. The evaporator and heater core are both housed within the module. The defrost outlet being open and closed by a defrost door, the side window outlets being open and closed by a plurality of demist doors. The defrost door and demist doors share a common shaft, a torsion spring around the shaft allows the defrost door to remain offset from the demist doors.

Abstract: A fan shroud assembly includes a fixed fan shroud and a removable fan shroud. An upper retention system integral with the fixed and removable fan shrouds secures the two circumferential ends of the removable fan shroud to the fixed fan shroud. A lower retention system integral with the fixed and removable fan shroud secures the center of the removable fan shroud to the fixed fan shroud. No additional fasteners are required to connect the removable fan shroud to the fixed fan shroud because of the integral nature of the upper and lower retention systems.

Abstract: A mounting arrangement for a heat exchanger in a vehicle includes a bracket having a main body. A first portion is secured to the heat exchanger and a second portion includes a mounting feature adapted to be secured to another component of the vehicle. A foot is formed on the first portion of the bracket. The foot defines an interface surface brazed to the heat exchanger in an installed position.

Abstract: A fastening system fastens a radiator, an electric fan support and a fan shroud as a single unit. The radiator has lower and upper posts to which slotted plates protruding from the fan support and fan shroud fit over. A structural sandwich is formed with the fan support lying between the radiator and the fan shroud. A flexible lever arm with a locking tab lies adjacent to the upper post of the radiator and connects to the radiator. When the fan support is fitted over the posts, the top plate of the electric fan support locks under the first lever arm tab. The fan shroud also has two slotted plates that also fit over the posts of the radiator. The fan shroud locks into place when a lever arm with a tab on the fan shroud locks under a tab that protrudes from the top plate of the fan support.
