Based on the parts listed at Autozone, I'd say this won't work.
The photos indicate the parts are physically very different.
Sorry...
There are 2 wiper motors on a Windstar: 1 for the front wipers and 1 for the rear.
The wiring, switch or blower has failed.
Check the fuse box. The front and rear blower motors are probably on different fuses.
There's one in each door.
Failed blower motor, resistor or switch.
I had the same problem and ended up replacing the blower resistor and the blower motor. Although it could be one or the other .. mine was both.
Perhaps resistor packs on blower motors is defective and need replacement
It won't have a relay. Usually it is the switch, or the fan motor that goes bad.
Windstar mini-vans are front wheel drive.
the relay switch is either under the rear seat or under the hood near the front right headlight,
YES , the Ford Windstar is a front wheel drive vehicle
the problem lies in the fuse, switch, motor, or wiring.
