Window off track

Can you show us any of the hardware in the window track. Can you also show us any pins at the bottom of the sash, called pivot bars like our selection here? Finally, I'd like closer pictures of those latches on the top corners of the sash. From there I'll see if we can help. 

Okay, let's slow down a bit. The window sash is the movable part of the frame with the glass. Those rods on the side are called spiral balances. They're spring-loaded mechanisms that regulate the opening and closing of the window. If they're broken then they absolutely should be replaced. Let's start with those, because in the process of replacing them you'll see other pieces you may need to replace as well. Watch the videos below for details, then get back to me.
