My electric windows on my 3.2 have stopped working.

[Glosaircooled]

The other day I noticed that the passenger electric window would intermittently not work, which I thought was odd, then today in with the wife in the car they have all decided to stop working, which made for a fun journey back. Iv checked the fuse which seems intact, but apart from that have absolutely no idea as to the cause. any advice would be greatly appreciated.
