My drivers side power window switch stopped working. The window would go about half way up then stop. This started a few days ago. The window would eventually go up when I continually try the switch. Today the window went down and will not go back up. This seems to be a common issue with this particular vehicle. Why hasn't Mercedes conducted a RECALL on this switch?!!
All window will not work,that included both side mirror. Will try to replace main switch on center console
i went online and repaired window switch myself. it took alot of guts on my part to take apart the entire console but with the detailed instructions from google i was able to do it.
Driver window went down but wouldn't come back up. Took blow dryer to switch and the heat caused the switch to make connection so window could go up. Replaced Switch @ 200.00
Power window circuit boasrd had to be replaced. Without warning driver window stuck in the down position
drivers side window doesnt go up. there is sound when i try to raise it but nothing happens.
after trying over and over for over ten min. i got it up some, then ten min. more of trying constantly, by pulling switch up to raise window, it finally went up all the way. now i leave it up, and i dont use the window.
i had a window switch replaced i think a few years back. i had the same exact problem.
now its faulty again
Driver window stuck down. Followed a suggestion with warming switch with a blow dryer (thank you to the person who posted the idea). Window went up and switch will be repaired at another time.
Had my window switch panel on my ml 320 replaced a couple of years ago at a cost of $1260.00. I had the same problem a month ago and purchased the switch panel on eBay for $36.00 and took me 30 minutes of my time to replace.
Driver side window would only go down but not up, had to replace the console switch assembly. This happened once in 2006 and then did it again in 2010.
Third time in two years the master switch was replaced and it failed on me again. The dryer suggestion worked but I know I can't roll down the windows again. It is a good temporary fix. Saved me $250 for the original part plus labor.

Thanks for the suggestion.
The Window switches are all in the center console and all the windows are down and will not roll up there is no way to get them up from the door
Drivers side window stuck in the down position. It's Friday evening, service mechanics done for the day, somewhere to go tomorrow morning, temps in the 40's. Read through the comments on Mercedes Ml320. Willing to try the blow dryer. Heated the switch for about 3 minutes. Long enough for it to get hot. Darn thing went up. Priced the new part, $179.00.
While traveling down Alaska Highway in early February 2017 at an outside temperature of minus 5 degree F drivers window would not go back up at Canadian customs station in Beaver Creek, Yukon Territory. Covered window with plastic laundry bag and duct tape and drove on to Whitehorse a distance of 285 miles. Tried the hairdryer trick mentioned on this site and it WORKED!! Will leave all windows up until windows master switch is replaced.
Just got home from the carwash. I had washed my 1999 Mercedes Benz ML320. I had the driver side window slightly down, but when I got home, I could not raise it all the way up. I could lower it but could not raise it back up. All other windows are working well.
