It's quick and easy!
On the inside of the door, opposite the mirror, there's a black plastic triangle. Pull on it from the top corner, it'll snap out. That gives you access to three nuts. Remove them (10 mm) and then the mirror should pull out from the outside. If they're power mirrors, then there's a connector you need to unclip, but it's painfully obvious.
Hope I helped! I can get pics tomorrow if you really need.
