Detailed Description

This HVAC recirculation door actuator is used to control the air door position inside the climate system, helping restore proper recirculation and mode-door operation. The Four Seasons 73251 is listed for 2013-2017 Chevrolet Equinox and 2013-2017 GMC Terrain applications, including 2014-2017 HVAC mode door actuator listings that control recirculation door functionality. It also covers 2013 models with the 6-pin connector second-design configuration. If you are replacing a failed Chevrolet Equinox HVAC actuator or a GMC Terrain recirculation door actuator, this part number 73251 is built for those confirmed fitments.

What It Helps Fix

• Recirculation door stuck in one position
• Inconsistent airflow direction from the vents
• HVAC mode changes that do not respond correctly
• Clicking or repeated actuator movement behind the dash
• Loss of proper cabin air recirculation control

Installation Notes and Tips

Verify the connector style, mounting ear layout, and door linkage before installation. Confirm the vehicle year, make, model, and HVAC configuration against the listed fitment for Chevrolet Equinox and GMC Terrain. Because this actuator is tied to specific HVAC door positions, matching the original part number 73251 and the 6-pin design is important for correct operation.
