Take command of cabin comfort with the Four Seasons HVAC Blend Door Actuator 73665, a direct-fit replacement for the LEFT-position actuator on a wide range of Nissan and Infiniti models. It fits many vehicles, among them the 2013-2017 Nissan Altima, 2016-2017 Nissan Maxima and 2017-2024 Nissan Armada — see the Buyer's Guide tab for the full list and engine details.

This blend door actuator is a small electric motor that drives the HVAC air door, positioning it to direct and mix airflow inside the heating and cooling case. When a worn actuator is the cause of clicking or tapping behind the dash, temperatures that won't change, or air stuck on one setting, replacing it puts door movement back under control.

  • Included components: includes the lever arm, gear, cam gear hardware and linkage as applicable.
  • Quality internals: built with an internal motor, drive gears, electronics and connections.
  • Tested: checked for function, durability and longevity.
  • OE-level build: made to match factory fit and function, backed by Four Seasons' long history in mobile A/C.
