99 mercury cougar replaced power window motor and switch window still does not work

That doesn't seem possible does it ?

You remove the inner door panel

You think the motor may be bad,so you unplug it,
knowing it is a DC Motor & can be hooked up either
way & will run in either direction
You put 12 volts to it. Doesn't work ,sounds bad,you
install a new one

Now you need power from the switch to run the new motor,
so you work on that
The switch can be disconnected & tested with an OHM Meter
& if worn,you replace that
You checked the fuse before you started & knew that wasn't an issue,
because all the other windows worked

So what did you mis ,short of having no wiring diagram, to make
things a lot easier?
