98 rear window regulator

[wtijr]

98 Regal LS

Both rear power windows have stopped working. The regulators (motors) work but the windows don't move. I suspect that the cables have come off track. I have pulled the door panels but I can't see where the cable loops around at the bottom.
Any idea as to where I can find some information (preferably diagrams/pictures) about how the power window system is supposed to look like. I prefer to see how it is supposed to look before I take it apart.

Thanks
