When a worn actuator leaves your climate control stuck on hot or cold, the Four Seasons HVAC Blend Door Actuator 73671 puts the blend door back in motion. This direct-fit Nissan Altima blend door actuator installs on the 2019-2024 Nissan Altima, 2020-2024 Nissan Sentra, 2019-2024 Infiniti QX50, and 2022-2024 Infiniti QX55.
An HVAC blend door actuator is a small electric motor and internal gear drive that rotates the blend door inside the HVAC case, controlling how much air passes over the heater core to set cabin temperature and airflow. This unit covers the left or right blend door position depending on the application.
- Complete drive assembly: includes the lever arm, gear, cam gear hardware, and linkage as applicable, with a quality internal motor, drive gears, electronics, and connections.
- Built to fit and function: matches OE fit and function for a clean drop-in replacement.
- Tested unit: checked for function, durability, and longevity, backed by Four Seasons' 50-plus years of mobile A/C experience.
Signs a Nissan Sentra blend door actuator may need replacing include a repeated clicking or knocking behind the dash, air that won't change temperature, or air stuck at one temperature. Diagnose the cause before replacing, since these symptoms can have other sources.
