Running backwards it's still a centrifugal pump but the vanes make it extremely inefficient. And I expect the geometry of the air intake and outlet ducts contribute to making air only flow one way.

That makes sense now that you say it. Is there an easy way to test without taking the car apart? Specified air flow at a certain fan speed or something along those lines?

They're a Chinese copy obviously but I'll keep the original anyway and see if it can be refurbished.
I might also look at constructing an "adapter" for the lead, rather than cutting the plug off the old one. Though it might be possible to just disassemble the plug if the contacts at the end of the wires are the same design.  |
Unfortunately, they are different. I had the same thought. The stock D2 connector is a pin connector, whereas the D3 connector is a blade type connector.
