Common Problems This Part Can Address

• Recirculation door stuck in one position
• Inconsistent cabin airflow direction
• HVAC clicking or repeated actuator movement
• Loss of proper heater or A/C air distribution
• Climate control response issues after actuator failure

Installation Notes and Tips

Verify the vehicle’s year, make, model, position, and HVAC notes before installation. Several listed applications require specific climate-control configurations, vendor matchups, VIN ranges, or build-date breakpoints, so confirm the original actuator details before replacing the unit. Inspect the connector style, terminal count, and mounting location to ensure the replacement matches the factory part.

Quality Assurance

Dorman designs this actuator as an OE-style replacement for the original HVAC component on the listed applications. The part is built to align with the factory actuator’s function and electrical interface for the specified vehicles.
