Detailed Description

This Four Seasons HVAC Air Door Actuator is designed for vehicles that use an electronically controlled mode door to direct cabin airflow. In the Cadillac CTS and Cadillac SRX, the actuator helps move the HVAC door between vent, floor, and defrost positions based on climate control commands. When the original actuator wears out or loses calibration, airflow routing can become inconsistent. Part number 73264 restores the specified actuator function for the listed vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Airflow stuck at one vent position
• Incorrect air distribution between dash, floor, and defrost outlets
• Clicking or repeated movement from a failing HVAC actuator
• Loss of response from the climate control mode door
• Uneven cabin airflow in Cadillac CTS and Cadillac SRX models
