Detailed Description

Four Seasons 73724 is an HVAC mode door actuator designed for 2015 Hyundai Sonata and 2016-2019 Hyundai Sonata applications. This actuator controls the position of the HVAC mode door so the system can route air to the correct vents.

This part cross-references ACT2074IM and DA1662 for the same application.

What It Helps Fix

  • Airflow stuck on defrost, panel, or floor settings
  • Inconsistent vent direction changes
  • HVAC mode door movement problems
  • Clicking or failed actuator response behind the dash
  • Loss of proper cabin air distribution in a Hyundai Sonata

This Four Seasons 73724 actuator is listed for 2015 Hyundai Sonata from 12/14 and 2016-2019 Hyundai Sonata, so confirm the vehicle build date and HVAC configuration before ordering. After installation, cycle the HVAC controls to confirm the mode door moves through all positions correctly.
