A-Premium HVAC Heater Blend Door Actuator Set of 3 — Main Blend Door, Direct-Fit for GM SUVs, Five-Pin Connector

Many vehicles use multiple actuators within the HVAC system; this set focuses on the main blend door actuator function. It arrives with a five-pin electrical connector, standard mounting tabs, and documented cross-reference numbers to simplify identification. A-Premium backs the part with a one-year unlimited-mileage guarantee for added confidence during installation and initial operation.

How do I know this actuator fits my vehicle?

Check your vehicle’s year, make, and model against the listed fitment: Buick Enclave (2008–2012), Chevrolet Traverse (2009–2012), GMC Acadia (2007–2012), and Saturn Outlook (2007–2010). Use the reference numbers provided to match your factory part and compare the actuator’s location and connector style with your vehicle.

• Compatible years and models listed above for quick verification
• Reference numbers: 604-140, 604140, 15232218, 20826182, 25782069
• Five-pin electrical connector to match factory harnesses
• Verify actuator location — vehicles may have multiple HVAC actuators

What does this actuator replace and what does it control?

This main blend door actuator moves the internal air-mixing door that directs heated or cooled air through the cabin. Replacing a faulty unit can restore balanced temperature distribution and correct airflow path selection when the original actuator is noisy, stuck, or unresponsive.

• Operates the heater blend door for temperature mixing
• Replaces common OEM part numbers for GM crossovers/SUVs
• Designed for direct-fit installation with factory mounting points
• Includes three actuators — useful for multi-actuator systems or future needs

What should I expect during installation and electrical fitment?

Installation typically requires basic hand tools and access to the HVAC housing under the dash. The actuator comes with a five-pin connector that aligns with the factory harness; ensure the orientation and gear engagement match the original part before final tightening.

• Simple bolt-on replacement using factory mounting locations
• Five-pin connector designed to plug into existing harnesses
• Confirm gear engagement and lever position before securing
• Professional installation recommended if dash removal is required

Who is this for: Technically minded DIYers, independent mechanics, and fleet service shops that need a reliable, cost-efficient replacement for the main HVAC heater blend door actuator in specified GM vehicles. The A-Premium set of three is also practical for owners who want spare units on hand or who manage vehicles with multiple actuators. Before ordering, use the compatibility checker and compare the listed reference numbers and connector type with your vehicle to ensure a proper fit.
