Application Details

Compatible with a wide range of Chevrolet Express 1500, Express 2500, and Express 3500 models, plus GMC Savana 1500, Savana 2500, and Savana 3500 vans across multiple model years. It also covers select Chevrolet G30 and GMC G3500 applications. This part cross-references FEL-PRO 73348 for the same application.

Use this actuator when the HVAC system needs accurate mode door movement for panel, floor, or main air distribution functions. The Four Seasons 73348 is a practical replacement choice for owners servicing Chevrolet Express and GMC Savana HVAC systems, especially when the original actuator no longer responds correctly to control inputs.

What It Helps Fix

• Incorrect air direction from dash, floor, or defrost outlets
• HVAC mode door movement that is slow, erratic, or unresponsive
• Temperature or airflow routing problems caused by a failed actuator
• Clicking or repeated movement from a worn HVAC actuator
• Loss of proper cabin comfort control in Express and Savana vans

Installation Notes and Tips

Verify the connector style, door linkage type, and mounting ear layout before installation. Confirm the vehicle’s HVAC position and application notes, especially on 2022-2024 Chevrolet Express and GMC Savana models where main and panel/floor configurations are listed separately. After installation, cycle the HVAC controls to confirm full mode door travel and proper airflow routing.
