Believe it or not, I had exactly the same problem with the dome lights doing that on an '89 Chrysler Fifth Ave. But after nine attempts to solve it, the problem turned out to be a one-of-a-kind defect that should have caused the fuse to blow except someone else had been in there earlier and modified the circuit. (Turned out to be a bare wire going to the passenger's visor mirror light. The visor would move forward 1/4" when braking and short that wire to ground, and move back when accelerating. Someone had found the circuit with the problem but instead of continuing to the defect, they cut and switched the feed and ground wires, so the shorted wire was now acting as a door switch in the ground circuit instead of a short in the feed circuit).
In your case, I would be looking at the door switches first. On some Ford models they are built into the door latches. If we assume that problem and the window problem are related, suspect the wires between the door hinges. Pull the rubber boot back and look for broken or frayed wires. Each front window switch will have its own feed wire, but both window motors go to ground through a common wire on the driver's door.
