Keep cabin temperature and airflow going where you set them with the Dorman blend door actuator 604-304, a direct-fit replacement that drops into the 2007-2012 Hyundai Elantra. This is the MAIN air door actuator position — it drives the blend door that regulates the heating and cooling flow through the HVAC case, so a failed or stripped original that leaves you stuck on one temperature or setting can be swapped without guesswork.
Direct replacement: engineered to drop in like the original air door actuator on the listed applications to restore proper HVAC operation.
Position specific: vehicles often use several different HVAC door actuators, so review this part's application notes to confirm it matches the location and function of the actuator you need to replace.
Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation and long service life.
Trustworthy quality: backed by a team of experts and engineers in the United States and more than a century of experience.
