2012 fiddy, had my windshield replaced today. The rear view mirror is not snug to the windshield after the re-install, shakes like a banshee while driving. It's obviously not tight on the metal tab which is glued to the windshield. I can't tell if it's not seated all the way or if the guy ruined the mount. Do I need to push/pull/otherwise to see if the thing might just not be locked into place? I have no idea how these new mirrors mount.

Had the same thing happen to me, I turned around and went straight back to the glass shop. Took the guy less than 2 minutes to fix.

Good deal, I was afraid he broke something. I'll hit him up first thing in the morning, makes me dizzy driving with my mirror like that.
