Four Seasons HVAC Blend Door Actuator,HVAC Mode Door Actuator P/N:73339
Keep cabin airflow headed to the right outlets with the Four Seasons Mode Door Actuator 73501. This electric actuator drives the HVAC mode door that routes air between the dash, floor and defrost vents, and it installs as a direct-fit, left-side replacement across a wide range of Hyundai and Kia models — including the 2016-2024 Hyundai Tucson, 2017-2024 Kia Sportage and 2019-2024 Kia Soul. See the Buyer's Guide tab for the full list of covered applications.
If air keeps coming from the wrong vents, the mode selection won't change, or you hear clicking or knocking behind the dash, a failed mode door actuator may be the cause — if so, this unit replaces it. Diagnose the source of the fault before installing.
