Hello, my right rear door window motor has gone.

Hello, my right rear door window motor has gone bad. The dealer told me that there is power going to it and told me the motor has gone bad. How easy/hard of a fix is this? I know I need to tear the door panel a part and plastic. Is it as easy as swapping out the old one and replacing it with the new one.I know there are some rivets (I believe) that hold it in place. Just wondering if this is a one man job and what exactly to do? Thank you!
