Detailed Description

This Dorman HVAC blend door actuator, part number 604-189, is precision-engineered to match the quality and performance of the original actuator used in select Chevrolet Caprice, Chevrolet SS, and Pontiac G8 models. It is designed for HVAC systems that rely on rotary actuator movement for blend door or mode selection functions, including applications requiring outside air control. For buyers searching for a Chevrolet Caprice HVAC blend door actuator or a Pontiac G8 HVAC actuator replacement, this part provides a direct-fit service option for the listed positions.

Compatible With 2011-2017 Chevrolet Caprice, Main; 2014-2017 Chevrolet SS, Lower Main; 2014-2017 Chevrolet SS, Main; 2014-2017 Chevrolet SS, Upper Main; and 2008-2009 Pontiac G8, Main. The Dorman 604-189 is also a practical match when replacing a failed actuator on Chevrolet SS HVAC systems with lower main, main, or upper main mounting locations.

What It Helps Fix

  • Incorrect air temperature from the vents
  • HVAC airflow that does not change between outlets
  • Blend door movement problems in the dash HVAC system
  • Loss of outside air control on listed applications
  • Clicking or inconsistent actuator operation

Confirm the vehicle year, make, model, and HVAC location listed above, since this part number 604-189 is used in multiple positions across Chevrolet Caprice, Chevrolet SS, and Pontiac G8 applications. After installation, cycle the HVAC controls to confirm proper blend door and mode operation.
