Rob Said :

There's a window relay behind the instrument cluster, according to MB electrical trouble shooting manual, as well as 2 fuses: 1 hot all the time, other hot on start/run.

Electric Windows      Posted by:  vwnate1@... vwnate1      Date: Fri Nov 29, 2013 6:50 am ((PST))               O.K. that's good ;        It still seems to me there's a power relay and the window power doesn't go directly from the Ign. switch .        There should be a cardboard inside the fuse box lid that details which fuse powers the windows ~ test that with your test light _before_ you touch the fuses ~ I can't tell you how oftn I find bad connections on the fuse box when the owner insists all is well .        Then you'll have to trace the power source from the fuse box , the wires are all color coded , prolly black with a colored stripe .        The wire you're looking for should have the same color stripe at the switch , that *one* wire where , if you apply power , all the windows work normally .        I wish I was more help than this ,electrical is always slow , deliberate work but very rewarding once you figure out where the open circuit is .        FWIW , the Performance Parts catalog shows what relay does what and where it's located , usually on the left front inner fender housing .        -Nate         Kevin Wrote:     Nate,   I already replaced all of the fuses with the good copper ones and cleaned all the contact points.
