2009 MINI Cooper R56 Mirrors Not Folding In

I bought a used 2009 MINI Cooper R56. I observed the controls for the mirrors, and they do adjust, but do NOT fold in when I turn the little knob clockwise/counterclockwise. I’ve pulled out all the possibly relevant fuses down in the passenger’s side, and they’re all working according to my fuse tester. How do I get them to fold in?
