Fuse 2 should have nothing to do with the windows and vice versa. (In the case of my '82 300D, the windows work fine with Fuse 2 completely removed.)
It seems that you are somehow getting window power to the wrong side of Fuse 2. (Otherwise, there is no reason why a Fuse 2 failure would affect window operation.) I think I would run a new "hot at all times" wire to terminal 30 on the window relay. If the problem persists, look for a short in the wire from the relay back to the fuse panel. (Fuse "b" and Fuse 2 are located next to each other.)
Another thought: remove fuse "a" and operate the fuse "b" windows (and vice versa) and see if Fuse 2 still blows. If it only blows on one pair, the problem will be narrowed by half. If Fuse 2 blows on both, it seems that the problem has to lie in the fuse panel or its associated wiring.
