Hey so about a week ago all the buttons on the driver side door as well as the mirror adjustment buttons to the left of the steering wheel stopped working on my 03 clk500. The window is slightly rolled down as it does when you open the door, however I can't roll it up fully as the only control for it is in the area that is impacted. Also the seat adjustment controls don't work. I can't roll down the passenger window with the driver's controls but the passenger window control still works. I checked the fuse boxes in the front right of the car and none of the fuses look blown. Any idea what part went on my car? If so do you think I can DIY it or do I need to take it to the dealership?

Thank you!

Check fuse 21 on the cabin fuse panel - end of the dash, driver's side. (or fuse 22 if RHD).

Yeah I tried that. Ended up being a control module failure. https://mbworld.org/articles/how-to-...s-replacement/

Here is a helpful article if anyone else runs into this issue. Haven't tried fixing it myself but I probably will as the dealership quoted it at $1300

Yeah, just buy a used one from another pre-MY2005 CLK. Should be plug and play.
