Four Seasons HVAC Blend Door Actuator,HVAC Mode Door Actuator P/N:73717
Four Seasons 37540 recirculation door actuator for the 2002-2019 International 4300 and other vehicles is the motor unit that moves an air door inside the HVAC system.
A door that sticks in one position, a clicking behind the dash, or airflow that will not switch between fresh and recirculated air can mean the actuator has worn out. A blown fuse or a damaged connector can leave a door stuck too, so these signs alone do not prove the actuator is at fault.
As an HVAC recirculation door actuator, it is a direct-fit replacement for the 2002-2019 International 4300LP and the 2013-2017 International Lonestar, along with other International models. If your vehicle is not named here, find its model, years and engine in the Buyer's Guide tab before you order.
