How do you fit a passenger door window on a 1991 vw polo?

The most common problem with Cabrio auto Windows is the Window regulator. Each window has it's own. My wife also owns a 2002 Cabrio, that had a mis-behaving window driver window and the passenger was locked in the up position. After inspecting the drivers window, I found one of the cable roller guides was broken, causing the cable to snag when using the window open / close, and resulting in the window seeming to have a mind of it's own. I had a local garage order the regulator for me, and then I disassembled the drivers door and installed the new regulator (problem is now solved).

The passenger window was bound up, I also had to remove the regulator and let loose the tension in the cable system by carefully removing the cover over the cable roller. This window works fine now as well.
