We just moved in to a house that has blinds built in between the window panes. We like them, but one of them is not functional (the blinds are closed, and rotating the dial that controls the blind angle doesn't do anything. I think I just need to replace the small unit that holds the dial. I took it apart and it appears broken. My issue is that I have no idea what brand these are to get started investigating how to DIY this. I know I could call the local window company, but that isn't really DIY, and I don't really want them to come all the way out to my house to tell me what kind of windows I have. See photos below.
