What It Helps Fix

  • Incorrect cabin temperature output
  • Airflow stuck on one vent setting
  • Blend door movement problems in the HVAC case
  • Temperature changes that do not respond to control input
  • HVAC system noise caused by actuator gear or linkage issues

Installation Notes and Tips

Verify the vehicle year, model, position, and climate-control configuration before installation. This actuator uses an arm linkage, 3 mounting ears, and a 5-pin terminal arrangement, so connector style and mounting points should match the original unit. For Volkswagen Passat and Volkswagen Beetle HVAC repairs, confirm whether the vehicle is left, right, or N/A position as listed in the fitment data, and check the dual-zone or ATC notes carefully.

Quality Assurance

Four Seasons supplies HVAC replacement components for application-specific fitment and connector matching. The 73423 actuator is cataloged to align with the listed Volkswagen Passat and Volkswagen Beetle configurations for accurate replacement selection.
