Detailed Description

This HVAC recirculation door actuator is used to move the air door inside the heating and air conditioning case, helping direct airflow between fresh air and recirculated cabin air. Four Seasons 73022 cross-references Dayco 73022 and is listed for a wide range of GM trucks, SUVs, and vans, including Chevrolet C1500, K1500, Tahoe, GMC Yukon, and Cadillac Escalade applications. It is also listed for Oldsmobile Silhouette, Pontiac Montana, and Pontiac Trans Sport models where equipped.

Compatible vehicle coverage includes 1995-2000 Chevrolet C2500, C35, and C3500; 1995-2000 GMC C2500 and C3500; 1999-2000 Chevrolet K2500 and K3500; and 1997-2000 Oldsmobile Silhouette. Additional fitment notes apply to certain Tahoe, Yukon, and Suburban applications, including models without ATC or with old body style HVAC configurations.

What It Helps Fix

• HVAC doors that do not change position correctly
• Recirculation mode that stays stuck on fresh air or cabin air
• Temperature control issues caused by a failed actuator
• Airflow routing problems inside the HVAC case
• Clicking or inconsistent door movement from a worn actuator

Installation Notes

Verify the connector style, female linkage, mounting ear count, and vehicle-specific HVAC notes before installation. This part is listed for N/A position applications, so match the original actuator location and confirm compatibility with ATC and old body style notes where shown in the fitment data. For best results, inspect the HVAC door and linkage for binding before replacing the actuator.

Quality Assurance

Four Seasons supplies HVAC replacement components for service applications, and this actuator is cataloged to match the listed OE-style fitments and interchange references for the specified GM and Pontiac vehicles.
