nomad and 2sparkys...Assuming the issue you mention involves the day/night shades, I found mine were just a little too tight as installed at the factory. This caused the cords on a few of the windows to fray from use. When re-stringing the first one which we broke, I realized I could just adjust all of them to loosen the tension enough to make them much easier to work. It is actually pretty easy to do. After doing so, we've had no further problems now for the past two summers.
