Stephen,

You have to be talking about the heater core.  You will have to take the glovebox out of the car and under it you will have to take the blower assembly out to get to the heater core.  You really need a manual.  I would go to the Nissan site and for $20 bucks you can download what you need for a service manual on your year car.  Also, if you just wanted the leak to stop for now you could loop the heater hose under the hood and bypass the heater core.
