HVAC Mode Door Actuator for Climate Control

Global Parts 1712320 is an HVAC mode door actuator for climate control systems that direct air to the selected vents. It is a direct-fit replacement for the 2005 Cadillac SRX, Mode Door Actuator; 2nd Design, and it supports precise vent selection when the system is calling for a change in airflow routing.

This part cross-references Dorman - OE Solutions 604-168 for the same application.

Key Features

  • HVAC mode door actuator for vent selection control
  • Moves the mode door to route air to floor, panel, or defrost outlets
  • Built for the 2005 Cadillac SRX, Mode Door Actuator; 2nd Design
  • Global Parts 1712320 replacement part number for service matching

How It Works

The actuator responds to the climate control head and positions the mode door inside the HVAC case. In this system, the blend door manages air temperature, the mode door opens and closes the selected vents, and the recirculation function controls cabin air intake. Global Parts 1712320 helps restore proper vent routing in the 2005 Cadillac SRX when the original actuator no longer moves the door correctly.

Common Problems This Part Can Solve

  • Airflow stuck at one vent setting
  • No change between panel, floor, or defrost modes
  • Clicking or repeated movement from a worn actuator
  • HVAC system not responding to mode changes
  • Uneven or incorrect air distribution inside the cabin

Installation Notes and Tips

Verify the vehicle is a 2005 Cadillac SRX with the 2nd design mode door actuator before ordering. Compare the original unit, connector style, and mounting points to confirm match with Global Parts 1712320. After installation, cycle the HVAC controls through each mode setting to confirm the door moves through all vent positions.
