My driver's side mirror feels rather loose. It's the actual housing that wobbles about the pivot point, NOT the mirror glass. I searched and found a few threads but they were mostly with regards to the mirror glass shaking. Are there a couple of screws behind the glass that might have come loose, or could it be something loose within the power fold mechanism? The passenger side feels pretty tight, no issues there. I do not have a power fold switch yet nor do I manually fold them in. Any help is appreciated.
