Car window displacement issue?

Hello auto-savvy people. 2005 Honda Civic. Tried rolling down the window and it basically got stuck and didn't roll down it seemed (happened while driving, hard to remember exactly). After it never rolled down, it basically "fell" inside the door with a big clunk while driving. When I was able to look at it, it basically looks like the the thing that actually goes up and down got detached from the actual window. I managed to slip it back in place per say and roll the window back up so that it is closed, but if I try to roll it down again, the window basically stays closed but then drops with a clunk if a fly lands on it. So basically, seems detached from the window motor. Can anyone confirm or deny my hypothesis? Anyone know how much it'd cost to fix? I plan to trade my car in and buy a new car within the next 6 months, so I'm trying to determine if it's worth fixing. If it's a simple, why not. Thank you!
