It's highly likely that one of the cable guides has broken off of the
mechanism.  They can be reattached with great effort, replacing the broken
rivet with a nut and bolt setup.
  Or you'll need to get a good used assy from a junkyard (HTF!), or buy a
new one from one of our list vendors.

Subject: Power window won't stay up

All of a sudden my power window on the passenger side won't stay up.  I
took off the door panel and saw that the window mechanism is not
connected to the wire cable that goes up and down.  And I can't figure
out how to reattach it.  The motor is working fine.  Any suggestions on
how to fix?
