Detailed Description

In vehicles such as the Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, and GMC Savana 3500, this actuator helps manage recirculation and mode door function so the HVAC system can direct airflow correctly. It also applies to additional GM passenger and commercial vehicles across model years 1991 through 2022. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
