Windows, only work from drivers door

Might be on to something. Wiring diagrams here, near the top of the page:

Take a look at figure 14.1 for the power windows. The two rear windows are controlled by the Rear Electronic Control Module (RECM). The front passenger's window is controlled by the General Electronic Control Module (GECM). The driver's window is controlled by the Driver's Door Control Module (DDCM).
When you operate the other three windows from the driver's seat, there is no direct electric connection between the driver's switches and those window motors. The DDCM is sending a message via data bus to the two other modules, which in turn operate their respective windows.
So a couple of thoughts:
Try unplugging the switch pack on the driver's door. Just a hunch, but if one of those switches is acting up, it might take priority over the individual switches at the other three doors. Not sure if this would knock out all three windows, but it should be easy enough to try.
Back to the wiring diagram, note how the three switches are wired. It appears they all get a common reference input from the RECM, connector CA102-5. The voltage isn't specified, but I'd guess 5V, a common value for such circuits. See the 59S inside a circle at the upper right corner? That legend leads to figure 01.5, and fuse #1 in the trunk. That fuse also controls the circuit to the rear window defroster, but if not working you may not have noticed in sunny Spain.
If that fuse is good, try individually unplugging the switches at the three doors. I'm wondering if a problem somewhere in that circuit could be drawing down the system voltage enough to affect the input the RECM and GECM are expecting to see when a switch is operated.
