the motor is loose on it's mount and it's gear is not engaging the window roller or the gear in the motor is loose or broken from the motor shaft. The window regulater is broken. You will need a new one. cost about 50.00 for parts and about that if you have it installed. glass speciality or a similar business can do it faster and without any problems.
If it is a older Crown Victoria,( had to replace a window in 89 grand marq.) you have to take off the door panel to get to the window motor and i believe also there are some springs too, and put it on track. Isn't much of a answer you was looking for but it's a start...
Yes
Check to see if you are getting power to the window motor- if so motor is bad If not check switch and wiring to same. Common problem is an open wire in the door hinge area
there is something wrong with your switch in the door you may have to change it
Yes
It's riveted in. Rarely do they fail. More often its the switch that fails.
You have a broken cable in the window regulator. You will need a new window regulator assembly.
what year?

On a 2000 Ford Crown Victoria : The fuel pump inertia switch ( shut off switch ) is in the trunk , behind the trunk liner on the drivers side ( there is an access hole )
try playing with the switch, and take it apart and clean it, they are famous for getting dirty, if that doesnt work, youll have to take the door panel apart and see if you're getting power to the motor when the button is pushed.
The complete moter and attaching bracket assembly inside the door must be replaced. as the bracket assy is broken.
