Hi Michael, under your dash next to your clutch pedal thier is a block of grounds you may find it easier to pop out your fuse box to get at them. Now I'm not sure that they are related to the windows but it is a good place to start. My windows along with pretty much all Alfa windows were slow too so I cleaned the connection in the doors as well as the window button itself and it seemed to help. I would suggest not taking the button apart. A bit of spray contact cleaner and some compressed air should do it.
