I have aluminum windows (about 14 years old) a few of which have a problem staying up. There is a tube on either side of the window attached at the top with a screw. Inside the tube is a spiral rod and what seems to be a spring. When the window is raised the spiral rod does not go into the tube as obviously intended which in turn does not allow the window to stay up. I tried reattaching the spiral rod to what seems like an anchor location at the bottom of the sash but it doesn't hold. Any ideas how to remedy this problem?
Thanks in advance,
