Detailed Description

Dorman 604-169 is an HVAC heater blend door actuator designed for select Cadillac DTS applications. It is built to replicate the original actuator’s function in the climate control system, helping regulate air temperature by moving the blend door to the requested position. This part cross-references AC Delco (e.g., 25770693, ADS4322) for the same application. For buyers searching for a Cadillac DTS blend door actuator, HVAC temperature control actuator, or Dorman 604-169 replacement, this part provides a direct-fit service option for the listed auxiliary position.

What It Helps Address

• Inconsistent cabin temperature from the HVAC vents
• Loss of hot or cold air blend control
• Clicking or binding from a worn actuator
• Auxiliary temperature control that no longer responds correctly
• HVAC system output that does not match the selected setting

Installation Notes and Tips

Verify the vehicle year, make, model, and auxiliary position before installation. Confirm the replacement actuator matches the original rotary-style design and connector layout on the vehicle. After installation, cycle the HVAC controls to allow the system to relearn actuator position if required by the vehicle’s control strategy.

Quality Assurance

Dorman engineers this actuator to match the quality and performance of the original blend door actuator on specific vehicle applications. It is intended as a direct replacement for the factory unit on compatible Cadillac DTS models, including 2006-2011 Cadillac DTS, auxiliary.
