Power drive system for modular dual pane rear-mounted window assembly

A modular window assembly mounted in a motor vehicle body comprising, in combination:

• a circumferential frame member mounted in a window recess in the vehicle body;
• a sliding subassembly comprising first and second sliding panes mounted in the frame member between first and second fixed panes, the sliding panes sliding laterally back and forth between their open positions and their closed positions;
• and
• a pull-pull cable drive subassembly for moving the sliding panes laterally back and forth between their open and closed positions, the pull-pull cable drive subassembly comprising:
• a drive apparatus mounted to the vehicle body remote from the frame member, comprising a drive motor having an output member and a drive drum operatively engaging the output member for rotation upon actuation of the drive motor;
• and
• a drive cable attached to the sliding subassembly and wrapped around the drive drum for pulling the sliding panes substantially laterally toward their open positions upon rotation of the drive drum in a first rotational direction, and for pulling the sliding panes substantially laterally toward their closed positions upon rotation of the drive drum in the opposite rotational direction;
• wherein the sliding subassembly further comprises a first cable guide operably connected to the first fixed pane, a second cable guide operably connected to the second fixed pane, a first cable fastener secured to the first sliding pane, and a second cable fastener secured to the second sliding pane, the sliding subassembly and drive cable forming a closed loop, with the drive cable extending from the drive drum to the second cable fastener through the first cable guide, from the second cable fastener to the first cable fastener through the second cable guide, and from the first cable fastener to the drive drum through the first cable guide.
