I just did this myself and it was easy, didn't even have to remove the door panel. I am not a mechanic and I did it in 15 minutes. This procedure also works with passenger side mirror.
1. Remove triangle shape cover inside the door by the mirror. I did it by hand.

3. Disconnect electrical connector prior to removal
4. Installation of mirror is just the reverse.
