I think I will have to stop by the dealer and ask to see the exploded diagram to figure it out, or perhaps I can find it online. The parts that I assume you are referring to as guides(blue plastic pieces that slide in the channels) are both there. One of them had the ball popped out of its socket, but I put it back and replaced the retaining clip(which was not on there), but that didnt solve the problem of the window not going up and down properly.
