Thanks for posting, Bill! I can't believe you still have these windows. I haven't worked on these since the 1970's. These are the old Air Control and are not made any more.

I used to fix them by removing the old bottom clip and spring button and replacing them with our 17-014 and 17-015 Bottom Sash Clips. I will post more detailed instructions below.

The balances you will need will have to be custom-made, which will require you to fill out some forms. I will post a link for each of the three balance lengths you require after the installation instructions.

Here's how you would go about installing the clips:
