I know a click bait title, but crazy story none the less. I had a very reputable 3rd party installer replace my windshield, but he did not notice a small wire harness had moved. When he was replacing the last bit of trim, the metal clip pushed through the wire for the auto-dimming to the rear and sideview mirrors!! They all turned black with electric-looking sparks. They had to replace all three mirrors!! Ugh. Something to make sure you mention to any 3rd party installer.
