Windows not staying open
I used your videos and parts that were recommended to me, attaching picture of parts ordered/ used...appreciate you for any help ypu can provide, thanks!
There could be two reasons why your window won't stay open. The first is that the replacement springs you bought do not match the strength of the old springs. The other is, as you presumed, a broken shoe. I would remove the shoe and closely examine the shoes to confirm if they are damaged or not.
Looks like your original photos were just of the stickers on the window, which don't tell us much. We can confirm what you have, but we would need photos of the original parts themselves.
I also can't see what you ordered. I see no purchased associated with the email you're using to post here. It's possible you used a different email address.
