Outside R.V. mirror replacement '02

[Willyum]

Appreciate any help to guide me to replace the left rear view mirror lens. I bought the part but hesitate to start because I don't want to break anything along the way.
Thanks in advance...
P.S. don't clean the mirror with an old razor blade, it's plastic not glass.

It's the lens /mirror only, NOT the housing - right? The lens simply pops out with enough force applied. The new one should snap right in. If it's heated, the connections will have to be made first of course. If the housing needes to be replaced, the door panel must be removed, to access the bolt on the bottom of the housing, underneath the (top of the) door panel. The bolt in the middle of the black triangular plastic cover on the inside (covered with a removable plastic insert/button) must be removed, but that alone will not free the housing, there are a total of three bolts holding the housing, per my recollection.

I used a small flat blade screwdriver insterted in the gap on the outside of the housing/mirror. Carefully release one of the plastic clips and press the screwdriver blade between the mirror assembly and base. The mirror popped off. Put some silicone lube on the clips and carefully snap the new mirror on to its holding bracket.
