I've learned a lot since the original post...but I haven't fixed anything yet. On my '92 right rear window, the cables were broken, but I couldn't figure out how they were routed. I discovered, after removing the "regulator assembly", how it all works, and how the cables are routed. The regulator assembly consists of the vertical track the window rides on, the cables, and the motor/gearbox assembly. This is all removed/installed as a unit. The motor bracket is held to the door by 3 rivets that need to be drilled out. The window is attached to a trolley that rides on the verticle track by 2 rivets that likewise need to be drilled out. Then, the vertical track itself comes out by drilling 2 rivets at the bottom of the track, and two nuts holding the top. (The rivets can be replaced with 1/4" bolts). To get the assembly out, the window needs to be removed first. This is easily done (with the two rivets already drilled out on the trolley) by popping out the inner bottom window seal, and partially pulling out the seal around the window opening in the door frame. Once the regulator assembly is out, you can see how everything is supposed to be attached, cables and all. I haven't found a good source for a replacement regulator yet, so I reinstalled the vertical track only, and reattached the window to the trolley. I'm currently using a small pair of vise grips on the verticle track to hold the trolley in it's highest position, which holds the window up.
