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?!!
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's side window motor stalls. The window won't roll up or down;have to do it manually.
Power window circuit boasrd had to be replaced. Without warning driver window stuck in the down position
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
All window will not work,that included both side mirror. Will try to replace main switch on center console
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
Blow dryer man I owe you a beer. Thank you because it worked.

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.
Drivers window switch went out. Replaced board. Ordered off amazon.

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.
Driver's window would not go up. I had the assembly replaced October 2012 and now (July 2014) the replacement has failed. The local Mercedes dealer says it is out of the one year warranty and I must buy a new part.

Three windows just went down & never came back up on there own I did nothing. Unplugged the unit & it allowed my smart key to roll all back up by holding the lock button at driver door.
