Keep your cabin's temperature blending under control with the Dorman blend door actuator 604-255, a direct-fit replacement for the 2011-2019 Ford Explorer, 2009-2019 Ford Flex, 2013-2019 Ford Police Interceptor Utility and 2010-2019 Lincoln MKT. This small electric actuator drives the HVAC blend door, positioning it to route air through the heater core and set the discharge temperature — this is the auxiliary-position unit.
- Direct replacement: built to install like the original air door actuator on the listed applications, no modifications needed.
- Position specific: these vehicles often use several HVAC door actuators; this is the auxiliary actuator, so check your application notes to confirm it matches the location and function you need to replace.
- Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for long service life.
- Trustworthy quality: backed by a team of experts and engineers in the United States, with more than a century of experience.
Signs the actuator may need replacing include a clicking or knocking noise behind the dash, air discharging at an inconsistent temperature, or airflow coming from the wrong vents. If a failed actuator is the cause, this Dorman air door actuator replaces it. See the Buyer's Guide tab for the full engine-level fitment.
