The driver's side wing mirror on my 2010 Sport is no longer folding when the button on the door is pressed. There's no motor noise or any other kind of noise coming from it. There was no problem with it before, and no hint that it was about to fail, I just parked the car as normal one morning at work and pressed the button and the driver's wing mirror didn't fold. However the passenger side wing mirror folds and unfolds no problem. Could this be just a fuse, or something more expensive like a switch or relay, or has even the wing mirror motor packed in? Like I said the mirror worked fine the day before, with no sign it was struggling or slowing down.
