I just bought a 2008 MB E-320 Bluetec and noticed that the rear window shade curtain is not working. It is now in the retracted position and does not go up.
I am going to troubleshooting by the fuses first but not sure where the fuses are located. I have one fuse chart saying that that is the fuses 24-31-41 inside the cabin. As this fuse chart is from a different year I am not sure if this is precise. I would appreciate a help if someone had this problem before. What is the first step that I should do ?
Thanks everyone.

I thought mine was broken too at first.

I would try pressing and holding the button in for several seconds, and see if that gets things moving.

Note that only the top half of the switch moves and so the same switch contact signals up and down.

I've found it's easy to get the thing confused and the cure seems to be pressing and holding the button for several seconds to reset it.
