Audi HVAC Blower Motor - Genuine Audi 4M1820021C

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 Genuine VW Audi

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VAG parts box and find an OEM branded part inside, simply with the addition of a VAG logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
