Detailed Description

Four Seasons 73616 is an HVAC mode door actuator engineered for vehicles that use electronic control of the air distribution doors inside the climate system. It is designed to move the mode door between vent, floor, and defrost positions so the HVAC system can route airflow correctly. This part is a practical replacement when the original actuator no longer responds accurately or the air direction no longer matches the control setting. Four Seasons backs this product with more than 50 years of mobile A/C experience and states that its components are engineered and tested for long service life.

This part cross-references A60616 and ACT1946IM for the same application.

Common Issues This Part May Resolve

• Airflow stuck on one outlet, such as defrost or floor
• Temperature or mode controls not matching the selected setting
• Clicking or repeated movement from a worn actuator
• Inconsistent cabin air direction in the HVAC system
• Loss of proper vent-to-defrost transition in supported Honda models

Installation Notes and Tips

Verify connector style, linkage type, mounting ear layout, and vehicle fitment before installation. Access to the actuator is typically through the HVAC housing, so confirm the replacement matches the original part number and terminal count. After installation, cycle the climate controls through each mode setting to confirm smooth door movement and correct airflow routing.
