Take command of your cabin comfort with the FOUR SEASONS blend door actuator (P/N 73715), a direct-fit replacement for the 2013-2014 Lexus GS350. This small electric motor drives the blend door inside the HVAC case, positioning it to control how much air passes through the heater core versus the evaporator — the mechanism behind your selected temperature and airflow mix. When a worn actuator is the cause of clicking or knocking behind the dash, inconsistent temperatures, or a door that won't move, this hvac blend door actuator replaces the failed original.
