New window regulator won't move?

I just bought a used 97 Honda Civic that drives perfectly. The driver s side window doesn't move however. I opened up the door and found that the window regulator was broken (the cable inside had snapped.) I bought a brand new regulator and when I plug it in and press the window switch, the regulator doesn't move at all. What can the problem be? I know that the switch is getting power because the old window motor turns when plugged in.

I know that window motors on newer cars need to be initialized. Is this the case for my 97 civic as well?
