Detailed Description

Dorman 604-315 is a heater blend door actuator engineered for specific GM HVAC systems that require precise door movement for temperature control, mode selection, or air inlet operation. Depending on the vehicle, it installs in either the main or auxiliary HVAC position and is listed for applications such as 2010-2016 Cadillac SRX, 2010-2015 Chevrolet Camaro, 2010-2013 Buick LaCrosse, 2011-2012 Buick Regal, 2012 Buick Verano, and 2010 Buick Allure. The Dorman 604-315 part number is commonly used when replacing a failed actuator that affects cabin airflow or temperature blending.

Common Problems This Part Can Address

  • Incorrect cabin temperature from a stuck blend door actuator
  • Airflow that stays on one vent setting instead of changing modes
  • Outside air or inside air door movement that no longer responds
  • Clicking, ticking, or repeated actuator movement behind the dash
  • HVAC control issues tied to the blend door or air inlet door

Installation Notes and Tips

Verify the vehicle’s HVAC position, connector style, and RPO code requirements before installation. This actuator is listed with a rotary switch activation type, pin terminals, and a 6-pin male connector layout, so matching the original electrical connection is important. Confirm the application by year, make, model, and HVAC position before replacing the original unit.
