I've got an '89 300E, same problem but fixed if only temporarily.
The doorpanels are screwed in only a few places, the trick is finding all the screws and knowing which direction to pull to get it out, as it is also clipped in.
I had to detach the interrior handle at its base, which was fairly difficult, as the top is bolted in in such a way that you can't get to it until you have the panel off. There is also a screw at the rear portion of the door where it latches into the frame. It doesn't look like it is holding the panel in, but it is.
Once you get the panel off, it is likely that the cablehas become disattached from the window mount. It takes a bit of finnagling, but if you loop the cable over the upper pulley, you can coil the spring tight enough to clip it back into place.
No parts were needed to fix either of my windows.
