This morning, my wife’s ML 320’s drivers side window stopped working. I drove over and thought that it might be a fuse.
I checked all the fuses and they were fine. The motor only seemed to click when you pushed the down button. When you try to raise the window, no noise. I thought it might have been the toggle switch, but I ended up breaking the black plastic cover to get inside. I still couldn’t get it lifted and as a last ditch effort(and because theres a 80% chance of rain today), I went by the dealership. He was able to stick a long piece of plastic in and raise the window easily.

My question is, can I buy just the replacement toggle switch? Or, is there something that can easily be added to fix? The technician told me that I would have to replace the entire board...since all the windows are on one switch, including the rear view mirrors...that sounds awful expensive and drastic since the only window is the drivers, and its obviously just the switch that’s bad since he was able to work the window...Also, if I do have to buy the entire circuit board, how hard is it to replace? Can I do it myself, or is it too complicated to go it alone on this one...? Thanks for your help.
