Dorman 604-113 HVAC Blend Door Actuator Compatible with Select Cadillac/Chevrolet/GMC Models

This mode door actuator performes excellent and was a perfect fit. Good quality and a great value. I expect its metal gear to be durable and long lasting. And even if it fails, its a Dorman part with a real warranty. I didn't have to take the dash apart to replace it so thats great but getting the levers lined up is not easy and if you have never done one I would leave it to a professional.

I installed it as it came in the box and the dorman cam plate was binding and not turning the gear unless i assisted it with my finger. As others suggested, i reused the old cam plate from the oem unit and installed it on the dorman motor and NOW it works as it should. Definitely was annoying considering my application was a 2000 chevy silverado which im sure many of my GMT800 brothers will come to recognize as being a difficult repair. Definitely dont take any chances with the dorman plate if you dont want to waste an additional 2+ hours of your time.
