Detailed Description

This Four Seasons air door actuator, part number 73129, is used in HVAC systems to move the recirculation door and control airflow routing inside the cabin. It is listed for 2000-2005 Buick LeSabre and 2000-2005 Pontiac Bonneville applications, including manual HVAC control configurations. For shoppers searching for a 2000-2005 Buick LeSabre HVAC recirculation door actuator or a 2000-2005 Pontiac Bonneville air door actuator, this part number 73129 matches the specified fitment details and connector style.

This part cross-references Global Parts Distributors LLC 1712075 for the same application.

What It Helps Fix

  • Recirculation door that does not change position
  • HVAC airflow stuck on fresh air or recirculation
  • Improper cabin air routing from a failed actuator
  • Temperature or vent mode control issues tied to door movement
  • Noise from a worn or binding HVAC actuator

Installation Notes and Tips

Verify the connector, linkage style, mounting ear layout, and HVAC control type before installation. This actuator is listed for manual HVAC control on the Buick LeSabre and Pontiac Bonneville applications shown, and one Pontiac Bonneville listing notes an ATC relay connector incompatibility with the HVAC blower motor resistor harness. Confirm the original part number and vehicle configuration against the fitment details for Four Seasons 73129 before replacement.
