Rear window of the Renault Scenic

Very good I have a problem with the rear windows of my Scenic 2, the floor was filled with water and the cream that carries under the seat was changed, it has been changed and well from the front control, driver's door, but the rear controls are crazy (do you give it to the right and lower the left or both at the same time) in the end that it is crazy, discouraged, there is some way of synchronizing them?
