W212 Erratic Window Switch Problem
The problem:
I put a window down half way by pushing down on the lever to first position until the window part way open. When I let off, the window stops. This works correctly as expected
I pull the lever up all the way to AUTO close the window. The window starts up, but when I let go of the switch, the window "springs" back down BEFORE it closes and continues on its way all the way down. When I let go of the switch, it should keep closing on its own. Even, assuming that the auto mode is not activated for some reason, the window should just stop in place when I let go. INSTEAD, IT GOES BACK DOWN.
This is especially problematic if there is snow on the window. Because once it starts going down, the snow get compacted. If the window goes down all the way, all the snow falls in the window. (sometimes I put my window part way down and then up to push up the snow and clear the bottom half of the window)
Today it happened with blowing rain and it took 4 attempt to get the damn thing to close and stay closed. By then, I was wet.
Like I said in the opening paragraph, it happened on my 2010. I figured it was a bum switch set. But it also happens on my new car. It pisses me off. But if it happens on both of my cars, there MUST be others here that are experiencing the same problem. Has anyone found a fix or even a reason for this? I am willing to put up with a lot, but this is a total fail for this caliber of car.
FYI, This has never been a problem in any other model of MB I've ever owned nor our current R350; only in the E Classes.

didn't do any good? Now you have THINNER glass?
. anyone has the same problem
?
I notice that if I don't try to put the window up quickly after putting it down it functions fine. However, quick button action results in the window going down first before going up. Truthfully, I think it's a big problem that MB is ignoring to recall (like their key batteries that go dead in short periods). I'm not sure I'm going to take it back and have them mess with it when it seems like most people haven't found the fix.

What makes matter's worse, is that they replaced glass that was tinted with 3M color stable film, without my approval. Dealer recognizes that this is a wide spread issue.
Any updates from anyone else?
I just came back from the dealer, and he reset my driver side window and now it can do a auto "UP" and close without a back down with a little gap. All he did was pulled up the switch (all the way up) for like 5 seconds and reset the UP position....it seems to fix now.
But I am sure the problem will come back again....after reading from all these threads. I can't believe this will happened on a $60,000 plus car. My minivan does not have that problem for sure...not even my 15 years old Toyota with 300,000 miles on it...
