Hi Dexter, All very good advice for 9000s, but a 900 mechanism is different. If you thought a 9000 mechanism was over-engineered, you really ought to take a look at a C900! The motor is *huge*, it drives a 3" cog via a worm drive, which turns a small cog, which drives a toothed quarter-wheel. This moves a pair of giant scisors, which raise and lower the window. No a pulley or cable in sight. The whole lot is rigidly fixed to the door, no rubbers. The only things I've seen go wrong are rusty motors and rusty 'scisor' mechanisms. The large cog is nylon, so I guess that could strip, but I've yet to see that, and I think I've probably fixed at least 10 dead 900 windows. -- Grunff
