I have a 2005 Nissan Sentra and the air is blowing out of the floor and vents. I can not get it to stop blowing out of the floor. I’m guessing my bend door actuator is bad.

I would like advice on how to replace the part and where it is located.

Yep, it sounds like the mode blend door is not moving, this is controlled by a cable, can I ask if when you switch the knob that controls the mode does it feel like it is doing anything or is it just spinning with no resistance? I would remove the HVAC panel to see if the cable is moving when you spin the control knob around. Please upload a short video in your response of the problem, so I can see what's going on

The knob is giving resistance like normal. It was working a couple months ago but no longer works now. I will try to get a video if I have time to pull it off.

These mechanisms can have issues because the plastic parts break, pleas go over this video it shows what I am talking about on a similar set up car.
