Detailed Description

This Four Seasons HVAC recirculation door actuator is built for vehicles that use an arm linkage and a 7-pin electrical connection to move the recirculation door inside the HVAC housing. It helps maintain correct airflow routing between fresh air and recirculated cabin air, which is important for temperature control, defrost performance, and overall HVAC function. For 2011-2013 Infiniti M37 and 2011-2013 Infiniti M56 models without the Touring Package, Four Seasons 73736 provides the correct actuator style and mounting layout for the application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Recirculation door stuck in one position
• Incorrect cabin air routing through the HVAC system
• Loss of response from the climate control actuator
• Clicking or binding from a worn HVAC door actuator
• Poor defrost or temperature control caused by improper air door movement

Installation Notes and Tips

Verify the vehicle is a 2011-2013 Infiniti M37 or M56 without the Touring Package before ordering. Confirm the actuator uses an arm linkage, 4 mounting ears, and a 7-pin connector to match the original unit. Access to the HVAC housing may require removal of interior trim panels, so compare the original actuator position and connector style before installation.
