HELP. Meriva window & sunroofs not working

[d4ve]

Need some help if anyone can?

Got a 2006 Meriva and all 4 windows and both sunroofs have stopped working Checked all the obvious,fuses etc. and all is good in that department.

I've been told that the problem could be the Body Control Module,which from the sounds of it ain't gonna be cheap to fix.

Anybody got any ideas as to the problem or a way of fixing it without having to pay vauxhall a ridiculous amount of cash (and I'm not going back to window winders)
