generally there are 2 speeds in a wiper motor. So depending which 2 wires of 3, it goes either fast or slow or really fast. The really fast option is not usually viable as it would damage the motor
As for turning different speeds in different directions, it is not normal and I have never heard of it. Sometimes the speed difference may be slight or the sound slightly different with direction, but usually not significant speed difference. I am not sure the exact cause, but maybe the motor itself is biased for one direction or the other. I would measure the current in both directions and play with the different windings. It would be interesting to see a video, however if the speed difference in direction is significant your best option may be to find a different motor.
