Detailed Description

This HVAC blend door actuator is designed for vehicles that use an electronically controlled blend or mode door to direct heated or cooled air through the cabin. Dorman 604-152 is built to match the original actuator’s quality and performance on the listed applications, helping restore proper HVAC door movement in Chevrolet Camaro, Cadillac ATS, Cadillac CTS, Buick Lucerne, and Cadillac DTS models. This part cross-references Standard Ignition ADR4216 for the same application.

What It Helps Fix

  • HVAC doors that do not respond to control changes
  • Clicking or repeated movement from a failing actuator
  • Loss of proper defrost, mode, or air inlet operation on supported vehicles

Installation Notes and Tips

Verify the vehicle’s HVAC configuration and position before ordering.
