Mercedes Blower Motor Resistor - Mahle Behr 2108206210

Product Information

The HVAC blower motor regulator is an electrical control component that manages the speed of the blower motor in the vehicle’s heating, ventilation, and air conditioning (HVAC) system. By adjusting the current flow, it allows multiple fan speed settings for proper airflow through the cabin vents. Typically mounted near the blower motor or within the HVAC housing, the regulator is designed for durability under repeated thermal cycles and electrical loads.

• Blower motor only works on one speed (usually high) – a classic sign of a failed regulator.
• No airflow from vents at certain or all settings – caused by an inoperative or burned-out regulator.
• Intermittent blower operation – due to failing internal circuits or poor electrical connections.

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.
