Detailed Product Overview
URO 4F0820521A is an HVAC blower motor resistor designed for Audi climate control systems that have lost one or more fan speeds. It is engineered as an OE replacement for the Audi R8 and Audi A6 platform, with fitment covering 2006-2011 Audi A6, 2005-2011 Audi A6 Quattro, 2008-2012 Audi R8, and 2014-2015 Audi R8. The resistor uses updated circuitry and durable construction to handle the moisture exposure common inside HVAC housings.
This part cross-references VEMO V10-79-0023 for the same application. The part number 4F0820521A also aligns with OE-style replacement searches for Audi blower motor resistor service.
Common Symptoms This Part Can Address
- Blower fan works only on certain speed settings
- HVAC fan stays on one speed or does not respond correctly
- Weak cabin airflow from the heater or air conditioner
- Intermittent blower operation caused by resistor failure
- Loss of climate control comfort in Audi R8 or Audi A6 models
Installation Notes and Tips
Verify the part number and vehicle application before installation. This resistor is a direct-fit OE replacement, so it is intended to connect to the factory HVAC harness and mount in the original location. Inspect the blower motor connector and surrounding HVAC housing for heat damage, corrosion, or moisture intrusion before installing the new unit.
Quality Assurance
Factory tested for proper performance, this URO blower motor resistor is built for long-term service in demanding HVAC environments. It is backed by a 24 Month Unlimited Mileage Warranty.
