I had a problem (85 300TD) with my two rear windows, no workee with console or door switches, fronts worked fine. No hot relays or fuse problems, but the wires in the harness going thru the pillar into the door were fried. The only sure way to tell is to push back the bellows at the door hinge, split the sheathing, and give a good yank on each wire. One or two in each door had corroded. My tech says it is a common problem. The insulation either looks fine or can't be seen for a length.

Maybe yours are shorting somewhere behind the scenes.

Just a guess, worth a look.
