My rear window sunshade is not activating. Can someone tell me if it is electric, hydraulic or something else? My dynamic seat function is not working and I suspect that I have a leak. If the dynamic seat circuit has a leak, would it affect the sunshade's operation? Thanks

the shade is electric

I had the same problem of my rear sunshade not working and found out that if I had someone push the button while I was in the back seat and pulled up on the sunshade it all of a sudden started to work.

That sounds like a good idea. I can hear something back there when I try to extend/retract. WIll try tomorrow.

Try to push the button few times...sometimes my doesn't work at 1st pressure, I have to push it again. It's electric I confirm.

Mine is crazy a bit, sometimes it works and sometimes it doesn't, until recently I tried something (doesn't sound relevant at all) that somehow made it work whenever it decide not to work.
There should a button that drops the back seats head rest (which doesn't work on mine btw) , I press that and hold it for like 20 seconds (I think it might be resetting something), after that rear shade works fine.

Crazy, isn't it?

I was fully prepared to start removing the rear seats, headrests, and deck and then disassemble the motor for the rear sunshade for my 2003 W211 E55.

I searched for the W211 instructions to do all of that (which I’ve seen on the forum before).

​​​​​​….and I found this post…AND IT FREAKING WORKED!!!

Thank you so much!

I hope you intentionally quoted my answer lol, if thats the case then this is great news! I mean despite how it works in the background but at least it worked 😂

Most probably it's confirmed then -as I read before- that it resets something.

Yes, it was your 20s push of the headrest-drop button that did it.

I have no idea how or why it worked...but it did.

How did you discover this?

Well, it was pure coincidence, I was actually searching for why the headrest-drop isn't working in my car, and someone was suggesting doing this 20 seconds thing as it resets something.
Then, and here's the interesting part, after that I pressed on the favorite button next to the headrest one by mistake (there's a small button with an asterisk that you can save a favorite action on), and guess what, it was saved to the rear sunshade action 😂 and it worked!!
I was freaking happy, then realized the relation here.

Now whenever the sunshade decides not to work, I just do that 20s thing and it works after.

Well, your happy accident helped me, too! Thanks!
