Does anyone have access to a wiring schematic for the power windows on a W123 (specifically a 1983 300D)? Suddenly both the front and rear right (passenger) side windows stopped working today. I know it is not the fuses as the right front window and left rear are on the same fuse and the left rear window works fine. Also the right rear and left front are on the same fuse and the left front works fine.

I suppose it could be the switch(es), went out, but what are the odds of them for both windows going out at the same time.

Any help is appreciated. I'm going to start probing around and do voltage and ground checks in the next day or so when I have time, so a schematic would be great.

Many thanks,

Glenn
