The right name is a Mode Door, it controls where the air goes. The Blend/Mix door is a whole different animal, it controls the outlet temperature. You're scrambling your terminology.swantzilla wrote: ↑Thu Feb 25, 2021 12:49 pmI have seen people call this a blend door actuator but is seems like it should be called an air diverter door. It may be that the controller does not know where the position of the actuator is and needs to be reset?
You are absolutely correct, I stand corrected...But you got me thinking,,,VStar650CL wrote: ↑Thu Feb 25, 2021 1:53 pmThe right name is a Mode Door, it controls where the air goes.

You're most welcome! Yes, in many of the modern systems the servos self-calibrate. When an electric motor stalls the current shoots up, so as long as the doors are healthy, the actuator can locate its own travel limits by watching the current flowing through the motor. In some vehicles like the gen2 Rogue the actuators are actually plain stepper motors and not servos, and the system has to be put through a "learn" algorithm in order to work right.swantzilla wrote: ↑Thu Feb 25, 2021 7:24 pmSeems like the Blend Door Actuator needs to run the motor till the door hits the end of travel to have it figure out where it is at. No wonder there are so many broken gears. Now I may soon need to find the air flow diverter actuator as I hear an occasional tic when I change the air outlets. Thank you for all your help.
