I just bought a 2008 MB E-320 Bluetec and noticed that the rear window shade curtain is not working. It is now in the retracted position and does not go up.
I am going to troubleshooting by the fuses first but not sure where the fuses are located. I have one fuse chart saying that that is the fuses 24-31-41 inside the cabin. As this fuse chart is from a different year I am not sure if this is precise. I would appreciate a help if someone had this problem before. What is the first step that I should do ?
Thanks everyone.
