Review on Air Blend Door Actuator Replacement for Chevrolet/GMC, OE: 89018365, 604-106, 52402588 - Compatible with 1994-2012 Silverado 1500 & 2500, Tahoe, Sierra - HVAC Heater Blend Control Motor by Edy Yukface

Works very well. I installed mine within a week, no problems so far. Once installed, I followed the reset procedure, removing the fuse and turning on the engine (you can study it to make sure you've picked the right one for your car). The one I got works perfectly and makes no noise where the passenger is still running. you make some noise. I'm not sure if this is due to the updated design or if my original is just a bit worn. Either way, this mixed door works well. I would change my rating if I had a problem with this product. So if there are no updates, most likely it's still working.
