New heat/ac control came in yesterday and I switched them out today and I have power to the blower again. 3rd shot from the cannon successful. Replacing the dash bezel I knocked the rear view mirror loose. I've always enjoyed replacing rearview mirrors, NOT. Also notice now that my side mirrors dont go up and down anymore so more shit to do smh.

What is this piece called that the metal disc for rear view mirror is attached to? If it’s needed what’s it for? It’s like a really thin aluminum pad maybe. (Apologies if a dumb question)

GM doesn’t show it as a part with the mirror, so it may be something that comes with the windshield to help the glue stick better.

Thanks. Google hasn’t been much help in giving the answer. None of the repair kits I’ve seen come with one either. I was thinking it was part of the mirrors readouts but it would have been on that chart. I’ve never known how the mirror reads the outside temperatures.

You can try posting your last 8 digits of the VIN and maybe @915_Tahoe can help.

That is part of the glass, the plate glues to that to have a better hold.

Up here to the right
Are replacements available? Does it even need to be replaced
I honestly dont think its even necessary…it probably helps adhesion and maybe even keeps the windshield from cracking in that spot (ive done that a long time ago) but Ive also glued countless rearviews to the plain glass over the years. Just make sure surface is clean and dry and dont put the mirror on before glue is ready.
