Fuse in the engine bay box fella.

The widows will operte with the door's open as that is the comfort relay loom which is separate.

As above: there are two fuses which deal with the windows - one in door open mode, and one in door closed. Both operated by the same switch, but different relays. Check all of your fuses, and if you find that you still cannot open your windows with the doors closed, get back to us and we'll give you some more help

Sadly I don't remember which fuse numbers they are, but the more time you spend checking this type of thing the better you'll get to know your car and the more you'll learn.

thats very good it is working, but why did it blow in the first place would be my next and more serious question? 30 amps is a big fuse!!
