Discontinued Louisiana Pacific window problems

A home owner from Michigan says:
Our home built in 1998 has LP windows. They are all double-hung tilt in windows. The sticker says product line 101-N. We have three windows that will not stay open. They just slam down. Is this something we can fix ourselves, not being extremely handy? What part(s) would we need to replace? One window is shorter than the others if that matters. I can upload a picture if needed. Thanks for any help you can give us!

It sounds like there may be a problem with the window balance. I will need pictures in order to help you. First, take a picture of the window itself. That is a good place to get started. Please also try to get a couple pictures of the balances; they should be located inside the jamb track on either side of the frame. They may be in a metal or plastic casing and they contain the springs and pulleys that are supposed to hold the window up once you raise it.
A home owner from Michigan says:
I'm not sure if these pictures will be enough for you. The first three photos show one window where the bottom section has one cord in place and the opposite side you can see the cord has broken.

The last two photos are of a smaller window. The top window falls down and the bottom window is very hard to move. I don't see any cords at all.

Please let me know if you need more photos.

I do believe we can help you repair this window, however we are having trouble finding an exact match for this balance. Is it possible to see the balance removed from the window to get a better look at it? It appears that it could be similar to our Series 770 but I'm not sure. I would also like to see what type of balance shoe you have, but the one you show is damaged. Do you have one that isn't? Send us some more photos a long with dimensions and we should be able to identify the parts needed. Thank you again for your patience!
A quick learner from Michigan says:
Can you give us a little instruction of how to remove the balance from the window? Also, not knowing much about windows, can you also explain what the balance shoe is?

Thank you for your patience. From what I can make out so far, I think you have some version of our Series 770 channel balance, though it may not be the same. You may also have a 15-129 pivot shoe. It's still hard to tell. I recommend watching the videos I've associated on the right side of this page. They may help give you some insight on what you can do.
