Restore proper HVAC airflow control with the Four Seasons HVAC Mode Door Actuator, MPN 73579. This electric actuator drives the mode door inside the heating and air conditioning case, positioning it to route airflow to the vents, floor, or defrost outlets on command from the climate controls. It installs as a direct-fit replacement for the 2000-2009 Honda S2000 — see the Buyer's Guide tab for full application details.

When a mode door actuator fails, air may blow from the wrong outlets, get stuck on one setting, or the unit may click or grind as the internal gears strip. If a faulty original actuator is the cause of those symptoms, this replaces it.

  • Engineered and tested to provide years of trouble-free operation, backed by Four Seasons' decades of mobile A/C experience.
  • Meets or exceeds OE specifications for fit and function.
  • Includes: lever arm, gear, cam gear hardware and linkage as applicable.
  • Quality internal motor, drive gears, electronics and connections, tested for function, durability and longevity.
