HEATER BOX ASSEMBLY / HVAC HOUSING

A heater box assembly is the main component of the vehicle heating and ventilation system designed to house the heater core, blower motor, air distribution flaps, and climate control elements. It ensures proper airflow management and temperature regulation inside the cabin.

The housing is installed inside the dashboard and works together with the heater core, blower fan, air conditioning evaporator, climate control unit, ducts, and airflow control mechanisms.

A damaged heater housing may cause weak cabin heating, unusual noises, air leakage, flap malfunction, windshield fogging, coolant leakage, or incorrect airflow distribution.

Our catalog includes heater box assemblies for many vehicle brands. Available options include genuine factory HVAC components, reliable aftermarket replacements, and tested used housings without cracks or deformation. Versions with blower motor, flaps, heater core, evaporator, and different climate system configurations are available.

Used parts are inspected for plastic integrity, mounting condition, absence of cracks, fastening damage, and sealing quality.

Selection is available by VIN number, climate system type, interior configuration, part number, and vehicle year. Replacing a faulty heater housing restores proper heating, ventilation, and climate control performance.
