rear window wont open or close

It the window doesn't work from either switch, Then its more than likely the window motor needs replacement. And you can get that estimate here www.repairpal.com/estimator choose window motor replace. But sometimes in a pinch ( with the door open you can hold the switch in the up position and hit the inside of the door panel with the palm of your hand hard ) and it will jar the motor loose enough to roll it up Hope this helps
