HVAC Mode Door Actuator Overview

Four Seasons 73744 is an HVAC air door actuator for auxiliary climate control applications. It is built with an arm-style door linkage and a 5-pin terminal layout for controlled air door movement in the system.

Compatible With Lexus LS460 auxiliary HVAC applications, this part number 73744 is listed for 2017 models and for 2009-2014 models with power slide seat equipment. Four Seasons 73744 is a direct replacement-style component for restoring proper air door operation.

Key Features

  • HVAC air door actuator construction for climate control air distribution.
  • Arm-style door linkage for actuator movement.
  • 5-terminal pin configuration for electrical connection.
  • Four mounting ears for secure installation.
  • Four Seasons part number 73744 for easy identification.

Detailed Description

This HVAC mode door actuator is used to control the position of an air door inside the climate system, helping direct airflow through the selected vents. The Four Seasons 73744 matches auxiliary applications listed for Lexus LS460 models, including 2017 vehicles and 2009-2014 vehicles with power slide seat equipment. If the original actuator is sticking, failing to respond, or no longer moving the door correctly, this replacement restores normal HVAC door control.
