I'll make it short. 1985 300D. Yesterday. One window lift pair works; the other doesn't. Must be fuse. I Switch window lift fuses. Same problem with same pair. Scratch head. Go to work. Today. I Look again at fuse box. I Look at fuse box diagram on cover again. I think, "What if...". I reorient cover 180 degrees. I switch those fuses. The windows work.

I repeat: Doh!
