2000 MC SS Electrochromic Mirror

Anyone ever had any trouble out of their rearview? Looks like mine has a spot that's not dimming all of a sudden, the rest is dimmed though.

It's kinda like a light bubble in the midst of the rest of the mirror being dim. The bubble has shifted from last night.

The mirror is just getting older and a little worn out. If it is really cold in your area it could be that the mirror is having a little trouble shifting. The only thing you can do is replace it.
