sorry, i missed seeing the obvious heading on the tiny phone screen.
now on desktop PC and it's obvious.
the springy steel wire is not the only fastener and it works in tandem with
the plastic nubs which snap fit the mirror backing onto the round plastic
part attached to the motor.
snap fit the mirror onto the round plastic motor plate. that, in itself, will
hold the mirror to the motor. it should not come loose even if you turn
and rotate the whole assembly around
attaching the mirror against the round motor plate emits a clear and
audible SNAP. if not, you've not secured it via the plastic perimeter
fasteners yet
next, the steel wire should easily pivot down and slightly over the edge
of the plastic motor plate. THERE IS A LATCH nub of plastic (green
arrow). if it is not there, it has been broken off. you can try JBWeld
something there with a tiny machine screw or ?
between the steel rod and the several plastic snaps surrounding the
mirror, those together help keep the mirror secured
the photo is from a 96-99 style mirror. I don't have access to the 00-02
at this time but the concept should be the same. that said, it is also
possible that your design is different than above which is why I ask
for a photo. We've been surprised in the past to learn that one owner
had an 00-02 mirror cover which fastened differently than one we've
seen for most 00-02 so it was very unique and we were otherwise
trying to provide typed solutions that only a simple photo could have
resolved earlier.
hope the above photo helps
