The problem I am having is that the blocks (nylon maybe) seem too loose on some of the windows and as a result they hang in the track and I have to go outside and use a thin screw driver to release them. I also think that I need to replace many of the slotted pieces that the arm work through, some are broken and most have the fuzzy stuff gone. I'll call the dealers this week to try to locate, I have looked all over the net but haven't found any so I was worried that they were not available.
Thanks folks, I appreciate the help.
