Last night my rearview mirror fell off and I don't know how to replace it. 1996 gle maxima any suggestions?

 

The mirror should have what looks like a big screw on the bottom and the roof should have a whiteish beige plastic mount with a metal clip in there.

There should be three screws holding this to the roof.

Unscrew all three of these screws and remove the plastic peice. Loosen the big screw on the mirror and attach the plastic peice to the mirror by putting the metal pin/clip thingy under the mirror's big screw and tighten the screw.

Now that it is all attached to the mirror as one peice, attach the whole thing to the roof again via the 3 screws (note if your mirror fell off you probably need to remove the plastic cover, screw in the 3 screws, then once it is mounted to the ceiling pop the plastic cover back on.)
