Keep your cabin airflow switching cleanly between fresh outside air and recirculated cabin air with the Four Seasons HVAC Recirculation Door Actuator, MPN 73618. This small electric motor drives the recirculation door inside the HVAC case on command from your climate controls, and it drops in as a direct-fit replacement for the 2015-2022 Chevrolet Colorado and 2015-2022 GMC Canyon — see the "Vehicles it fits" section for engine-level coverage.
When the internal gears or motor in the original wear out, the door can stick, buzz, click, or stop responding, leaving air stuck in one mode. If a failed actuator is the cause, this unit restores the door's motion.
