How It Works

In HVAC systems, actuators move doors that regulate temperature, vent selection, and recirculation. This Global Parts 1712324 unit is used at the inlet door position in the blower housing, where it helps the system open or close the air intake path based on the climate setting chosen by the driver. It cross-references Dorman OE Solutions 604-159 for the same application.

Common Symptoms It Can Address

• Air intake stuck on fresh air or recirculation
• Improper cabin airflow routing
• HVAC mode changes that do not respond correctly
• Clicking or repeated actuator movement from the dash area
• Loss of climate control response at the inlet door

Installation Notes

Verify the vehicle is a 2008-2009 Cadillac CTS before ordering. Confirm the actuator location as the inlet door actuator in the blower housing and compare the connector, mounting points, and calibration requirements with the removed unit. After installation, cycle the HVAC controls to confirm proper door movement and airflow response.
