it is a known problem here in UK too! i called mb rescue service. the lady said this common and gave me tips on how to bring the wondow back up by using quick pulls on the switch. no luck though.
called UK benz dealers and they will not honor this as my car in USA! i really am against buying another benz.

Another fine example of MB standing by its product (not)

Yep,
I've had the switch problem also - luckily my ML was under warranty at the time.
Makes me wonder what happens next time it fails and it's out of warranty ?
Probably fix it myself, the part is fairly cheap and I read it's only a 10 minute job. No point paying MB labor prices and minimum charges etc.

Like many others, this is my first & last ML - just going to run it into the ground as it's hardly worth anything as a trade in .....

If you ever get stuck with an ML window that won't come back up, here's what you do. First, and this may hurt you to do it, you have to break off the driver's window switch. Trust me, it's already broken, no more harm will be done than is done already. Just pull back hard and the switch will pop off. Under that, there's a white piece held in by a tab on either side. Spread the tabs slightly apart, and the white piece comes out as well. Once you have both of those off, you're going to see three electrical tabs in the recess where the switch used to be. Take a non-metallic item such as a toothpick, reach in and push down on the right (or left, I can't remember off-hand) tab, the window will come back up. Make sure you use a non-metallic item, or you will short out the switch and blow the power window fuse.

Almost 100% of the time, it's the switch.

mbtech208 rules!!

Northern Wisconsin. 30 degrees on April 16 and we are supposed to get 1-3 inches of snow tonight. Dealer is 115 miles away and the drivers window is stuck completely down on my wife's 00 ml430. Vehicle is 875 miles out of warranty. I consulted the board, found this thread, broke the top off the switch, removed the white plastic cap, and used the top off a plastic pen (nonmetalic) to raise the window!!! For future reference the tab on the right (facing forward) raises the window and the one on the left lowers it.
My MB is with out a doubt the biggest automotive dissapointment I have ever had. At 49,000 the vehicle went in for it's last service and was gone through from top to bottom. The list of problems fixed is endless. We have been debating on trading for an X5 and now the debate is over. Cost difference by the time you add the neccessary options is only $4000 and while it isn't in the budget I was reminded today of what a piece of junk this MB really is.
mbtech208, THANK YOU. You saved me driving to the dealership tomorrow with a vehicle wrapped in duct tape and plastic.

Have the same window problem.At first I noticed the smears on the glass,thought it would eventually get better. Now the window has stuck or the switch has broken.

I can feel the clicking(barely) when I pull on the window switch.Is it the switch,or is it stuck from the insulation melting away?
I hate to rip the switch apart if that's not the problem.Need help....it's starting to rain .

Thanks
David

OMG thanks for this post. This my third time having to replace the switch panel. Went out completely today and could not get window back up! Found this and followed the directions exactly except I used a toothpick. Thank you, thank you, thank you!!#
