Keep your Honda's climate system switching cleanly between fresh outside air and recirculated cabin air with the Four Seasons HVAC Recirculation Door Actuator, MPN 73637. This small electric motor drives the recirculation blend door inside the HVAC case, positioning it in response to the climate-control settings. It installs as a direct-fit replacement for the 2006-2011 Honda Civic and 2008-2011 Honda CR-V — see the Buyer's Guide tab for engine-specific coverage.

  • Complete unit: includes the lever arm, gear, cam gear hardware, and linkage as applicable.
  • Internal build: motor, drive gears, electronics, and connections.
  • Built to OE-level fit and function for a clean drop-in replacement on the listed applications.
  • Tested for function, durability, and longevity, backed by Four Seasons' decades of mobile A/C experience.

Signs the original recirculation door actuator may need replacing include a repeated clicking or knocking from behind the dash, air that won't switch between fresh and recirculate, or a door stuck in one position. If a failed actuator is the cause, this hvac recirculation door actuator restores motorized control of the door.
