A quick learner from OCALA FL says:
Several of our windows no longer stay up and (clever) husband says we need a replacement spring or mechanism in order to fix them!? This were put in when the home was built in 2004.

Attached is order info/label from one of the windows -can you replay which what parts we need to replace in order to get the bottom half of window to stay up and link to any available instructions?

Ready to ORDER from you folks! Thanks in advance,

Unfortunately, this sticker does not tell us what you need. The only way to determine what balances will work with your window is to compare physical details, such as design and dimensions. If you were to show me a picture of your balance out of the window, we should be able to identify it. Thanks!
