rs window problems?

anyone know what i need to do to get the window fixed? what happens is my window rolls up almost all the way, then it feels like the crank is slipping, when i close the door, the window drops about 1-2". it didnt bother me before, but now that its starting to rain more often, waters coming in since it lowers just below the weather stripping rubber part. do i need a new door? or just a “crank” or whatever its called, i took the door apart, but couldnt see anything, tried adjusting the 4 nuts in the tech tips, that didnt work.

Check the guides on the side of the window.Check for breakage of the aluminum.
