The rear passenger window opens spontaneously when I am locking the car. It is then impossible to close the window again using the electrical buttons.

This fault seems to correct itself spontaneously too. I switch off the engine. Lock the car with the window continually staying down. After approximately one hour. I go back open the car - start the engine and then I can open and close the rear passenger window using the electrical buttons

Had to laugh reading this!! My megane opens the driver window and then refuses to close (not fun when it's raining) it will then close only if I open the passenger window, which then won't open for and hour or 2.
Check that there is nothing stuck in the window slides as the safety mechanism will bring the window down if it meets resisitance. Reset your windows by opening the passenger window then pressing and holding the button down for 10 seconds. then open and close all windows one at a time. Alternatively, sell the car, they are rubbish (worst I have ever owned)
