Keep cabin airflow moving to the right vents with the Dorman - OE Solutions HVAC Blend Door Actuator 604-251. This air inlet air door actuator drives the door that positions HVAC airflow, and it installs as a direct-fit replacement for the 2011-2019 Ford Fiesta (see the Buyer's Guide tab for engine-level fitment). It fills the MAIN air-inlet position, so review the application notes to confirm it matches the actuator location and function you need to replace.
- Direct replacement: engineered to install like the original air door actuator on the listed years, makes, models and configurations to help restore proper HVAC operation.
- Position specific: vehicles often use several different HVAC door actuators for different positions and functions — this one serves the MAIN air-inlet location; verify the application notes before ordering.
- 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.
Signs this actuator may need replacing include clicking or knocking from behind the dash, air that won't change source or temperature, or an inlet door stuck in one position. If a failed air inlet actuator is the cause, this replaces it.
