windows, headlights, blowers not working

[jaybo]

as the title says the electric windows, headlights inc mainbeam and heater blowers have suddenly packed up.
i have checked every fuse on the vehicle and checked the wiring that i could see. the battery is fully charged.

the van has had in the last 12 months 2 alternators, alternator loom, a new battery plus lots more £££££££££££££££'s spent on it all over and i'm starting coming to the point where a can of petrol and a match is tempting.

can any of you nice people shed some light on my problem.
thanks
in advance
