My 1989 260E has an odd window issue. The front left and right rear power windows refuse to operate. The other two and the sunroof work great. Do you have a schematic and/or trouble shooting guide for them?
The problem could be wiring or switches or ??? So an electical schematic would be most helpful.
Thanks

 

Left front and right rear are on the same fuse. Check for blown or corroded fuse first.

 

Nickspa is correct, they are on the same fuse. Check that out.

Here's the schematic.

It's not the clearest, but hopefully it'll help.

If you're using Internet Explorer as a web browser you may have to click on the little icon in the lower right hand corner of the schematic to expand it. See the pic below
