Detailed Description

This HVAC actuator kit is designed to restore proper movement of the air doors that direct cabin airflow and temperature blending. On select Chevrolet Silverado and GMC Sierra applications, as well as Cadillac Escalade EXT and Chevrolet Avalanche models, the actuators help manage the transition between vent modes and temperature settings so the HVAC system can respond correctly to driver input. Dorman ADAKIT009 is a practical replacement for vehicles that use the listed factory configuration, including models without RPO Code D07 (Custom Front Floor Console) where specified in the fitment data.

This part cross-references ADK108 for the same application. Dorman ADAKIT009 is also listed with interchange references 89018365 and 89018374 for related coverage.

What It Helps Solve

• Incorrect airflow direction between dash, floor, and defrost outlets
• Temperature stuck on hot or cold due to blend door control issues
• Recirculation door movement problems affecting cabin air selection
• HVAC mode changes that do not respond consistently
• Actuator-related clicking, binding, or loss of door movement

Installation Notes and Tips

Verify the vehicle’s year, make, model, and HVAC configuration before ordering. This kit is listed for specific Chevrolet Silverado, GMC Sierra, Cadillac Escalade EXT, and Chevrolet Avalanche applications, with fitment notes that include wo/RPO Code D07 on many listings. Confirm connector style, terminal count, and mounting location against the original part before installation. Because fitment varies by trim and console configuration, use the vehicle identification details to match the exact application.
