Does it have heated mirrors? A heated mirror has 2 wires connected to it. To remove the glass you need to pry it off. The glass is glued to a plastic holder and the glass/holder assembly just clips on. By hand, adjust the mirror all the way down to create a gap between the top of the glass/holder and the outer shell. Use a flat blade screwdriver (wrapped in a towel to prevent scratches) to pry it off. Be sure to put the screwdriver on the plastic holder and not directly on the glass. Once it pops off, disconnect the wires. The new glass/holder will just snap back on. Just remember to reconnect the wires. If it's not a heated mirror, there will be no wires but the rest of the procedure is the same.
