Product Details

The Four Seasons Air Door Actuator line focuses on HVAC control components that manage airflow direction inside the cabin. Part number 73143 is used to move the air door in the heating and air conditioning system, helping the HVAC case direct air to the proper outlet or recirculation path. In Dodge Ram 1500, Ram 2500, and Ram 3500 applications, this actuator is listed for the right position and for dual zone climate control systems with recirculation door actuator requirements.

For buyers searching by vehicle and position, this part number 73143 is a practical match for right-side HVAC mode door service on 2002-2008 Dodge Ram 1500 and 2002-2009 Dodge Ram 2500 or Ram 3500 models.

Common Problems This Part Can Address

  • Incorrect airflow direction from the dash vents
  • HVAC system stuck on one outlet setting
  • Recirculation door movement failure
  • Temperature or mode changes that do not respond properly
  • Clicking or inconsistent actuator operation behind the dash

Installation Notes

Verify the vehicle’s HVAC system, right-side location, and connector style before installation. Compare the existing actuator’s arm linkage, 2-ear mounting pattern, and 3-pin electrical connection to confirm match. On Dodge Ram 1500, Ram 2500, and Ram 3500 trucks, access is typically through the HVAC housing area behind the dash, so careful removal and alignment of the door linkage are important for proper operation.

Quality Assurance

Four Seasons is a recognized aftermarket brand for HVAC service parts, and this actuator is cataloged to match the listed vehicle applications and interchange references for direct replacement use.
