I wasn't able to because the Mercedes repair shop i went to tried to rob me by basically saying "i have a weak brake caliper in the rear and its 500 to fix," and after that they can work on the CAN BUS. Any who i went to my brothers shop and he fixed it on the alignment lift, went back to them and they told me "I don't wana work on your car." Anyways I know a supra guy who worked at Mercedes thats going to look at it on their free time, but i was brainstorming about the windows and if the windows always work when i restart the battery except the sunroof, then the sunroof is faulty and causes the front windows to stop working, since they're on the CAN BUS.

Also, I believe mickey13 has a pretty good set of the ground points for the w202 if you need help finding those
This is the door control module ( N69/1 )
These are the diag. steps for your driver window
these are the diag steps for your driver side mirror

Thanks for your input ill check into it. On the other hand I'm attacking the p1747 error and it boils down to the instrument cluster, so i removed it and I'm going to replace it with a fresh one, my cluster is missing bulbs that have to deal with the SRS, and the warranty seal has been tampered with. I don't think any electronic issue in this car has to do with bad continuity because it's never been in an accident or been pulled apart from what i can see, so their can't be any wire breaks. Most of the problems stems from old modules that have problems with relays clicking over due to age. In a case with my seats when i got the car the seats would move when they want to, now that i replaced the relay it works all day and night. The windows all work, but the sunroof never worked, and that leads to the windows working on Monday and only the front windows and mirrors not working by Friday. Ill keep an update.

Any updates? I have a similar problems, windows go out intermitently until i plug and unplug the battery, i don't have the x37 connector, It's either the sam or the control modules in each door, if fixing-replacing the sam doesn't fix it, i will look at the window control modules, as the rear window motors are disconnected and still the failture is the same.
All have X37 it's in the passanger side footwell under the glove compartment behind the plastic panel by where your right leg would be if you were in that seat. Aside from that, it's simple just change all the motors in the door. Car is old that's all.
