Detailed Description

Four Seasons 73747 is an HVAC blend door actuator used in climate control systems to move the air door that regulates heated and cooled air distribution. The actuator’s linkage style, mounting ear layout, and terminal count are important for proper electrical and mechanical matching during replacement. For Mitsubishi Lancer, Outlander Sport, and Outlander fitments, using the correct actuator helps restore consistent cabin temperature control and airflow direction.

The Four Seasons 73747 is backed by more than 50 years of mobile A/C experience and is engineered and tested for long service life. If you are replacing a failed HVAC blend door actuator on a Mitsubishi Lancer, Outlander Sport, or Outlander, this part number 73747 provides the fitment-specific configuration needed for the application.

Common Issues This Part May Address

• Inconsistent cabin temperature
• Air stuck on hot or cold
• Improper airflow direction from the vents
• Clicking or ticking from the HVAC housing
• Loss of blend door movement

Installation Notes and Tips

Verify the connector style, terminal count, linkage type, and mounting ear layout before installation. Confirm vehicle fitment by year, make, and model, since this actuator is listed for 2007-2017 Mitsubishi applications with specific model coverage. Compare the original unit to part number 73747 to ensure the replacement matches the existing HVAC actuator configuration.
