The rear windshield washer pump on a 2001 Ford Escape is typically located
in the rear of the vehicle, under the cargo area carpet. It's often near the area where the washer fluid reservoir lines run to the rear. You'll likely need to remove some carpeting or trim panels to access it.
However, there's no guarantee of the exact location without looking at a repair manual specific to your year and model. The location might vary slightly depending on trim level or other minor variations. A diagram from a repair manual would be the best way to pinpoint it.
