Rear view mirror removal
Thank you tRustyK for repying, but my 1999 Blazer has no set screw, it uses a clip. Now, for anyone else trying to remove their mirror, I have found a nearly perfect (and cheap) tool to press the underside clip with. My 11 year-old daughter thought of it far sooner than I could; a plastic orange peeler, found in the kitchenware section of some stores. It is soft plastic, with a curved tip. Press the tip against the clip so that the plastic bends, and wiggle upwards with the mirror until it slides off. The orange peeler will undoubtably break far sooner than the windshield, so no worries!
