2002 Nissan Pathfinder Now Fan

My girlfriend came home today and said there was no heat in her pathfinder. I checked it out and there was no fan. I checked both blower fuses and hotwired the blower relay and still nothing. I think I hear the fan turning slowly when the heat is on but if it is, it's not fast enough to throw out any heat. There's also no change when I remove the fuses or the relay. What's the next check?
