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 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

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.

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.

Driver side power window will not close. Replace switch.
Driver side power window won't close. Will go down but not up.
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.

The driver side switch was loose about 4 to 5 years ago. So I kept a piece of tape on it which worked until 4/15/16. It totally broke off.
The Driver's side window stops working, all the other windows are working fine. This has happened about 20 times since purchase. Thankfully the warranty and extended warranty covered all the replacements of the unit. The center console unit that controls all windows has to be replaced since it is one piece. Finally a defect was determined by Mercedes. Unfortunately, it went out again and costed me $400 to replace by former Mercedes mechanics. Going to stop using the Driver's side window.

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.
