Product Details

Four Seasons 73304 is an HVAC blend door actuator used in auxiliary climate control systems that route air through the center console for second-row passengers. It is listed for 2014-2019 INFINITI Q70, 2015-2019 INFINITI Q70L, 2012-2013 INFINITI M35h, 2011-2013 INFINITI M37, 2011-2013 INFINITI M56, and 2007-2015 Mazda CX-9. This part number 73304 is also cross-referenced to 604460 and BDAC1274 for the same application.

What It Helps Resolve

  • Incorrect airflow direction from the auxiliary HVAC system
  • Temperature blend issues in the rear center console climate control
  • Loss of response when the HVAC control module commands door movement
  • Sticking or inconsistent air door operation
  • Noisy actuator operation behind the dash or console area

Installation Notes

Verify the connector, 5-pin terminal layout, male linkage, and 4-ear mounting pattern before installation. On Infiniti Q70, Q70L, M35h, M37, and M56 applications, this actuator is used in the center console for 2nd row climate control; on Mazda CX-9 applications, confirm the auxiliary air door location matches the original unit. Compare the original actuator’s indexing and mounting points to ensure proper alignment during replacement.

Quality Assurance

Four Seasons is a recognized HVAC parts brand, and the 73304 actuator is cataloged for direct replacement use in the listed vehicle applications. Confirm fitment by year, make, model, and auxiliary position before ordering.
