I get this a lot. Even when I pull away I push on my memory button and I see the mirror move to it's normal position. Such little things can be such a nuisance lol. I want to attempt this clean and grease job but my only concern is getting the glass out without cracking it or chipping the edges. Maybe a hook type of tool to get around the outsides and hook to the plastic backing and pull outwards?
I dunno, seems like something I'll screw with and break what isn't broken.
Maybe when I get bored or wake up hungover, I'll find myself doing this.
Thanks for the fix though, I thought sometimes someone was touching the mirror somehow or I was slamming the door too hard or something.
