Try acetone for the adhesive, put it on a rag and hold it on the sticky stuff and let it melt, minimal rubbing required.
Try acetone, it won't damage the paint/clear coat and will dissolve the adhesive.I've tried both goo gone and denatured alcohol very briefly. I'm worried about using strong solvents since they'll probably eat the paint just as easily.
I've seen rubber wheels that go in a drill that are supposed to remove adhesive well, anyone tried one of those?
I don't know, but I think some Saabs had heated mirrors, so maybe that was the white connector?Which makes me wonder, there were two round connectors to the mirror, a white one and a black one. I thought the black one handled the adjustment motor and the memory. What does the white one do?
I took another look. Both LH and RH mirror have "grey" (looks white to me!) connector both ends, car harness and into mirror. H10-1 and H10-13. Two wires in positions 1 and 2, for autodimmingMy door mirrors do none of that.
