I have a 1999 BMW 528I sedan. The rear passenger power window at first had trouble going down and then up. Now it fell down and I had to manually lift it back into place. Is it just off track, or with my "average" abilities as a mechanic, can I tackle the job of replacing parts? Thanks in advance!

 

Optional Information:
1999 BMW 528I v-6

Already Tried:
nothing

Unfortunalty, it is not off track, most likely the Power Window Regulator has broken and no longer supports the window. This isn't a difficult repair, once you get over removing the door trim panel.
