Audi Blower Motor - Mahle Behr 4B1820021B

Product Information

The HVAC blower motor is a key component of a vehicle's heating, ventilation, and air conditioning (HVAC) system. It is responsible for pushing air through the vehicle’s HVAC system, circulating either heated or cooled air into the cabin through the vents. Without a functioning blower motor, air will not be properly distributed, making it difficult to heat or cool the interior of the vehicle. A failing blower motor will make it difficult to control the temperature and air circulation in your vehicle, leading to discomfort in extreme weather conditions.

• Weak or No Airflow from Vents: One of the most common signs is reduced or no airflow when you turn on the HVAC system.
• No Response from HVAC System: If you turn on the HVAC system and there is no response (no sound, no airflow), the blower motor may have completely failed.

About Mahle Behr

Mahle Behr GmbH & Co. KG is a German corporation active in the automobile industry, headquartered in Stuttgart-Feuerbach. It is a specialist for automotive air conditioning and engine cooling systems. Mahle began in 1920 when pistons made of heavy gray cast iron were being used in internal combustion engines for automobiles and there was a need for a new design. The Mahle brothers countered this trend by producing light-alloy pistons at their small, newly established company however the technology was still finicky and problems come up frequently. They soon determined that they needed to come up with a solution to keep dirt and dust out of the engine so they eventually developed air and oil filters as well. Their perseverance paid off and the light-alloy pistons began to take over the market. Today, half of all automobiles produced worldwide contain MAHLE components. MAHLE offers an extensive range of parts for everyone including pistons, cylinder liners, piston ring sets, bearings, assemblies, valves, valve train components, and air, oil, fuel, and cabin air filters. Their catalog and online database of aftermarket engine components is an indispensable reference.In early 2016, Stuttgart-based MAHLE GmbH increased its holding in the Behr Group from 36.85 percent to approximately 51 percent with the acquisition of all shares in the BWK GmbH holding company. The company now goes by Mahle-Behr.
