Blend door actuator

This sounds like the mode door actuator has failed this time. So the way this works is the blend door controls the air temperature and then the mode door (air outlet control servo) controls the direction of the air floor.

The process is basically the same but the motor is in a different location. Here are some guides that will help with this info but if you just replaced the blend door then you may not need this:

However, below is the location of this motor which will help with accessing it.

Please let me know if you have other questions. Thanks
