There weren’t any articles on Hometalk so if you find this helpful could you maybe post it on here?

Most likely they need replacing. I don't think there is anything you can do to fix them.

If there is an inside screen put clear plastic or drop cloth. Otherwise thermal drapes. It would be tedious but self stick weather stripping on each glass pane would help give a better seal placed so rain doesn’t break the seal.
