Swap out a stuck HVAC blend door with the Dorman blend door actuator (P/N 604-118), a direct-fit replacement engineered to drop in like the original air door actuator on the 2000-2005 Buick LeSabre and 2000-2005 Pontiac Bonneville. This is the MAIN position actuator — the small electric motor that drives the blend/air door so the HVAC system can direct airflow and mix heated and cooled air per the temperature setting.

Because these vehicles often use several different HVAC door actuators for specific positions and functions, review this part's application notes to confirm it matches the location and function of the actuator you need to replace; if you're unsure of the position, consult a qualified service technician.

  • Direct replacement: built to duplicate the original air door actuator's form and operation on the listed applications.
  • Position specific: serves the MAIN air door position — verify against your vehicle's application notes.
  • Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation.
  • Trustworthy quality: backed by engineers in the United States and more than a century of experience.
