Carefully break it out. It's only held in by silicone so once you get some
of the pieces broken away, you can get a blade in there and cut it. Get it
all out, clean everything up and glue new one in with silicone.

Yes, in most cases the mirror glass can be replaced without pulling
the mirror off the car.
First, you need to determine whether that mirror has a heated glass
or not. Many of the higher-line GM cars like the Park Avenue have
heated outside mirrors. You can determine that a number of ways: one
is to look at the SPID label (on the inside of the trunk lid or on the
spare tire cover) and look for a code that begins with "DC' through to
"DR". Those are outside mirror codes. Post that code in the newsgroup
and I'll look it up for you.
Next, depending on the type of mirror, either the glass comes out of
the frame OR the glass and its backing pop out of the mirror motor
drive unit. You can usually tell which kind by moving the mirror to
one extreme and look at the back side of the glass. If the mirror
glass backing is flat, then the mirror probably just glues onto the
backing. If the backing looks like it has 3 or 4 "buldges" in it, then
the mirror and backing plate pop into the drive unit (the heated
mirrors use this type of mounting).
Next stop is the dealer to get a replacment glass and backing
assembly. The dealer will need the SPID code for the mirror to
determine which mirror glass you'll need.
