We own a Thor Compass and found the shade to the skylight over the cab totally unwound and sagging. It will not rewind. I was hoping it was like a home shade where I could take it out of the brackets and turn the ends to tighten the springs, then replace it. Unfortunately, that doesn't seem to be the case. Does anyone have experience fixing or replacing one?
I watched a tech work on ours, its full of cables, pullies and springs. Once you get the frame around it off, you should be able to see the mechanics. When I looked in there, it seemed over complicated, but maybe not. Good luck.
