When I pluged in the new motor it rotated clockwise and stopped. It will rotate back no matter what the vent selestor is set to.

there are no vacuum lines on this model for a/c, it uses dc servo motors to operate the blend door and the fresh/recirculating vents.

Is the dc motor maybe hooked up backwards? That would make the motor turn in reverse.
