Four Seasons 37537 recirculation door actuator for the 2000-2013 Chevrolet Silverado 1500 and other vehicles moves the recirculation door in your HVAC system, so the cabin draws either fresh or recirculated air.
- Meets or exceeds OE specifications for fit and function.
- Has a quality internal motor, drive gears, electronics and connections.
- Tested for function, durability and longevity, and engineered for years of trouble-free operation.
- Backed by over 50 years of mobile A/C experience.
A failing actuator can show up as clicking behind the dash, a door that stays in one position, or air that won't switch between fresh and recirculated. These signs alone don't prove the actuator is at fault, since a broken door can act the same way.
It also fits the 2000-2014 Chevrolet Silverado 2500 and the 2000-2013 GMC Sierra 1500, along with a wide range of Chevrolet, GMC, Buick and Cadillac models. If your vehicle isn't named here, look up your own year, model and engine in the "Vehicles it fits" section.
