My unit is only one month old and came with the Slow-Rise window shades. This morning I went to raise one and heard the weird quick noise and the shade would not raise because the spring is sprung.
I don't know it is broken totally or not. I watched a video on You Tube on adjusting it so I rolled it by hand and finally got it to stay up. I went to town, got back in the heat of the day, tried to lower it and as soon as I did it all rolled out again like this morning.
Any ideas on how to fix it? It is very difficult to get to it and it is not like one in your home that you can just pop out and rewind. This is on a Sierra 371 rebh. It is the shade above the sofa.
