I would suspect that the wires are connected backwards at the blower motor. Many of the aftermarket blower motors come with wire extensions coming out of the blower motor and going into a harness connector. The original motors have the plug built in with no wire lead extensions. You would need to remove the wire terminals from the connector body and swap the positions.
