CLK 320 Window not working

[XC3113NT]

So my driver side window isn't working, I removed the interior doorside and checked if the motor is stil working. And it is, it seems that the whole window mechanism isn't working as intended. But before changing it, is there anyone else that might give another advice to check something else? The window when using the button moves like a millimetre up and down, and won't seal properly against the bodywork. The motor turn the cogs och the window mechanism but nothing else moves. So any advice on what to check or change, or maybe even just change the whole mechanism right away.
Info: CLK 320 C208 "99/"00

Thanks before hand

Try putting the power directly into the motor to see if it works.

The motor still works, it turns the cogwheel that's on the window mechanism. It's just that when it turns the cogs nothing else happens so I don't know if the cogwheel should bring the other stuff with it while it's turning or not :/
It still sits in the correct place but it seems it's just turning on nothing.

Sounds like you need a new window regulator

Alright, just as I expected but worth a try if anyone else had some other thoughts.
But thanks anyways.
