Keep your cabin airflow switching cleanly between vents, floor, and defrost with the Dorman - OE Solutions HVAC Blend Door Actuator 604-304. This is the main mode air-door actuator, and it drops in as a direct-fit replacement for the 2007-2012 Hyundai Elantra (see the Buyer's Guide tab for engine-level applications). The small electric motor drives the HVAC door that directs where conditioned air flows; when it fails you may notice air stuck on one setting, clicking or knocking behind the dash, or temperature/mode changes that no longer respond.
- Direct replacement: engineered to install like the original air door actuator on the listed years, makes, models, and configurations.
- Position specific: many vehicles use several different HVAC door actuators for specific positions and functions — review this part's application notes to confirm it matches the actuator you need to replace.
- Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable, long service life.
- Trustworthy quality: backed by a team of experts and engineers in the United States, with more than a century of experience.
If a failed mode actuator is the cause of your airflow trouble, this unit replaces it. Confirm the position matches before ordering.
