Keep your climate system moving air to the right temperature with the Dorman - OE Solutions HVAC Blend Door Actuator 604-818, a direct-fit replacement for the 2012-2018 Volkswagen Beetle, 2012-2015 Volkswagen Beetle Cabrio, and 2012-2018 Volkswagen Passat. This is the MAIN, LEFT MAIN actuator — the small electric motor that positions the blend door to control how much air is heated or cooled inside the HVAC housing. If a failed blend door actuator is the cause of inconsistent temperature, clicking behind the dash, or a door stuck on one setting, this unit replaces it.
- Position specific: vehicles often use several different HVAC door actuators, so review the application notes to confirm this matches the location and function of the actuator you need to replace.
- Direct replacement: built to fit and operate like the original air door actuator on the listed applications.
- Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation.
- Trustworthy quality: backed by a team of experts and engineers in the United States, and more than a century of experience.
If you're unsure which actuator position your vehicle needs, consult a qualified service technician. See the Buyer's Guide tab for the full fitment and engine details.
