Can you roll up the window manually on a powered until get new motor for Ford Windstar?

No, you generally cannot manually roll up a power window on a Ford Windstar (or most other vehicles with power windows) if the motor is broken. The power window mechanism is designed to work with the motor; there's no backup manual crank. You'll need to get the motor replaced to be able to operate the window again. Until then, you'll need to leave the window closed (if it's up) or find a way to temporarily secure the window in its down position to prevent theft or weather damage.
