I have removed the mirror glass from the housings several times. Adjust the mirror all the way to the left and down and you can release the top catch with a very small/slim flat bladed screw driver or paint can tool (available at the dollar store or free from Benjamin Moore paint store). Now adjust the mirror all the way to the right and release the other top catch. Adjust the mirror all the way up and release the bottom catches, each side. unplug the wires and there you have it!
