AC at driver footwell not blowing (passenger side footwell is)

[westfaliacamper]

MY LX470 blows cold air from all upper dash vents, and the little "crotch" vent under the steering wheel seems to operate as well. However, when I adjust to have the AC blow onto the footwell areas, only the passenger footwell receives air...nothing for the driver footwell area. Some preliminary research suggests a servo motor failure or possible carpet interference. I would think if the servo motor failed, my passenger footwell would also not be receiving air. Anyone else experience this and have a solution?

Check the carpet, common for it to be pulled up over the vent.
