Four Seasons HVAC Defrost Mode Door Actuator,HVAC Mode Door Actuator P/N:73512
Take control of your cabin airflow with the Four Seasons HVAC Mode Door Actuator (P/N: 73579), a direct-fit replacement for the 2000-2009 Honda S2000. This electric actuator drives the HVAC mode door that directs air between the defrost, vent, and floor outlets — when the original fails, air can get stuck at one set of vents or the mode selection stops responding, and you may hear clicking or knocking behind the dash. If a failed mode door actuator is the cause, this unit replaces it.
