Power window question

1964 Imperial, are the power window motors left and right, or it doesn't matter?
I've slowly been getting the windows to work , the front windows roll down when you push forward on the switch (which seems backwards to me) and the one rear I've gotten working rolls down when you pull back on the switch
Since the wiring harness only plugs into the motor one way, I wondered if the motors are left and right?
Or any other ideas why the controls are different between the front and rear windows?
