Dismantling rear door, 95 S320

[hodag]

I have a power window problem and I have looked at enough threads that I think I know what I have to do with the mechanicals. My problem is getting the face panel off the door to expose the system. There are a few illustrated guides that show how to do it for other models, but I can't seem to find one for the W140. On the E series, there are three screws, one near the door release, one at the latch plate and one by the pull handle.

So far I have but I have managed to locate the one by the latch and one inside the armrest / pull handle assembly (hiding beneath a small cover plate). I have popped the little plastic holders on the sides and bottom, but something feels like it needs to be removed near the top of the pull handle / armrest. Dang if I can find where the screw is.

Can somebody give me some pointers on opening this up? Does the little cup around the silver colored door release come off?My window is stuck in the down position and winter is coming!
