HVAC question. Please help

[jreask]

With the AC on if I press the recirculate button the volume of air from the vents doesn’t change. In my other 4Runners pressing recirc increased the amount of air coming from the vents. Seems to be no change when pressed.
Is there a door stuck ? Thanks in advance

This might get you in the right direction. Most seem to act up by putting out a false signal so they jump back and forth (click). Sounds like yours has just failed or is stuck in one position.

Good Luck
