I got the passenger side mirror off of that Suburban today. It was actually about the only mirror that wasn't broken on all of the trucks there other than one that was a heated variety. The finish is quite sun-faded on this mirror, and the glass has a scuff on it that I've tried to show in one of the photos. The mount hinge is good and tight. The motors do work. Here's a video of them in action.

I also grabbed the center console latch out of the same vehicle.
If you are wanting a nicer-looking mirror, I totally understand. I have 30 days to return it for a refund.
