One thing to note, never wind down your window fully on a proton car. This is one way to prolong the life of any proton power window that tends to break down after a while if kept letting the power window auto stop to fully open position.
Keeping a sheet of clear plastic and some strong tapes might be a good idea too, so you don't get caught pants down when it rains and you discover that your window does not wind up anymore.
Good luck.
