Passenger window "off track"; do I get to it from inside panel or outside car?

What is your question?

Power windows work, but actual window is not properly affixed to mechanism. Therefore, when lowered, it only goes down to a point, and then will not close without manually straightening it (if I'm lucky). I want to try to repair this myself, and have gotten conflicting info online about whether the window and mechanism can be reached from the inside of the car or the outside. Any help appreciated. Thanks.
