Broken sash stop and top latch

Hello! Your top sash guide here looks like our 18-161. I've never seen one in the same brown color as you have here, though. Ours is only available in white or black.

As for the latch being difficult to operate, that could be a symptom of multiple possible factors. Your first step should be to remove it from the window and see if it operates normally by itself. If it still hangs up then it is definitely the culprit and should be replaced.

If it works fine, though, then the issue is probably with how the sash is aligned in the frame, and could be clue to a much bigger issue. In fact, the damaged top sash guide may very well have caused such a misalignment. In my opinion, you should try replacing the top sash guide first and see if that fixes the problem.

If not, let me know and I can see if we can figure something out.

That's fairly common. It doesn't change the removal process, though. You still need to get those channel balances under the take out clip. It just takes some elbow grease to push the balance down.
