My driver side mirror is loose and wobbles around on its support arm/neck thingy on its own. At high speeds it is visibly shaking. The power fold function does not work, unless I give it a nudge, then it will automatically fold in or out. I've tried cycling it many times, giving it help, and it always moves if I help it but will never start on its own.

From my searching it seems the common mirror fixes were for the old style mirrors, not what is on my 08. Does anyone know where I should start?
