Direct conditioned air exactly where the climate controls command it with the Four Seasons HVAC Mode Door Actuator 73520. This electric actuator drives the MAIN mode door inside the HVAC case, positioning it to route airflow to the vent, floor, or defrost outlets. It installs as a direct-fit replacement for the 2007-2017 Lexus LS460, 2008-2014 Lexus LS600, and 2008-2014 Lexus LS600h — see the Buyer's Guide tab for full engine-level details.

  • Includes: lever arm, gear, cam gear hardware and linkage as applicable.
  • Quality internals: internal motor, drive gears, electronics and connections.
  • Tested: checked for function, durability and longevity.
  • Built to OE-level fit and function, backed by Four Seasons' 50-plus years of mobile A/C experience.

Signs the main mode door actuator may need replacing include clicking or knocking behind the dash, air coming from the wrong outlets, or airflow that won't switch between vent, floor and defrost. If a failed actuator is the cause, this unit replaces it — diagnose the mode door and linkage before installing.
