I just did my drivers door window. It sounds like the upper guide on  the
regulator is broken. That would allow you to lower the window but there
would not but anything to pull against to raise it. A bently manual is
helpful here. The door comes off, the plastic water shhets come off, the
motor regulator is dismounted then manuvered through a hole in the door.
this involves rotation of the part while being careful not to break the
plastic parts of the regulator. I was able to fix the broken fasteners on
the regulator and get it working again. It is time consuming and there are
some things I found in my job. If you feel compelled to try I can give you
a more detailed description.
