Window Issues

So, My girl was winding down the passenger window to talk to me, and i heard *bang* and the window stopped operating.

Upon coming back to the car, I (in hindsight, probably idiotically) pressed the button to try to make it work. It went down when I pressed up.

I assume this is a general issue with the make and model, as both back windows have been... made manual by a previous owner.

Any idea what's wrong? What will it take to bring it back to factory spec? and what can I do in the mean time to make my life liveable? (see: air conditioning)

Keep in mind i live in Sarasota Florida, it rains every day at approximately 4PM, and it's hotter than hades the rest of the day.
