Motor and switch works but window won't roll down in 1995 crown Victoria?

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.
