I have done it several times and can tell you it is not as simple as the videos make it seem. Most things inside the door are attached with rivets so plan on drilling them out. Working space is very tight and at times you wish you had a little kid to reach in some the the places that you might need to access. As mentioned, check voltages at the switch and motor etc, before you begin removing anything. Generally, there are not separate fuses for each window, just one for all. It is doable, but pretty involved, especially your first time.
