Detailed Description
Four Seasons 73753 is a replacement HVAC blend door actuator used to control air distribution and temperature blend functions in the cabin HVAC system. For Acura TLX models from 2015 through 2020, left-side fitment is confirmed, making this part a direct match for the listed application. The actuator’s arm linkage, 4-ear mounting design, and 7-pin terminal configuration support proper mechanical and electrical integration. This part cross-references Interchanges (e.g., 79160TZ3A41, 79160TZ3A42) for the same application. Four Seasons 73753 is a practical choice when the original actuator no longer responds correctly or the HVAC system needs restored door movement.
Common Issues It May Solve
- Incorrect cabin temperature blend.
- HVAC air not directing properly through the vents.
- Actuator clicking or failing to move the door.
- Loss of response from the climate control system.
- Stuck or inconsistent air door operation.
Installation Notes and Tips
Verify the left-side application, connector style, and mounting layout before installation. Compare the existing actuator’s terminal count, mounting ear pattern, and linkage style to Four Seasons 73753 to confirm match-up. After installation, cycle the HVAC controls to confirm smooth door movement and proper temperature change.
