Rear Window does not work

I have a 2004 Toyota Tundra with extended cab and the rear window behind the rear seat has stopped working. It is closed, thank God. The owner's manual is no help in locating the fuse that might be the problem. Can anyone help me locate the fuse or have any idea what might be wrong?

there should be two fuse boxes, one under the hood and one under the steering column...both should have a cover on which the fuses should be labeled
