I don't think the motor is fried. Sounds like maybe when the window fell, it unplugged the wire. If you unplug the passenger side switch, the driver side switch for the passenger window doesn't work either (strange for parallel connections, but.... anyhow). The window is falling because the clamps came loose. I think you should take your door apart and glue your window back in its clamps and also check out your wiring at the same time.
