It should be behind the rear vent.
There would only be a rear heater core if there was a rear heater, which I don't believe was an option.
The rear heater core is on the right side of the vehicle. It is behind the side panel just rear of the wheel.

The front heater core is inside the front hvac housing, under the dash. The rear heater core is inside the rear hvac housing, behind the interior panel on the passenger side rear.
Front heater core is in the dash, the rear heater core is all the way in the back of the vehicle. If you have steam coming out of the dash vents, the front HC is leaking. If you have steam coming out of the rear heater vents, then the rear core is leaking.

The front heater core is located behind the dash on the passengers side and heats up the front section and the rear heater core is located in the rear located behind the passengers side rear panel and it heats up the rear section..........

YES. It is behind the plastic panel in the rear of the vehicle.
There are two heater core hose that goes to the firewall the inlet and outlet. through that hose, you will also have the rear heater core hose attached to a T joint in both the inlet and outlet hose. You splice the hose of the front heater core inlet and connect that to the rear heater core inlet hose. Same goes to the Outlet hose with the T joint using a conncetor which you can buy at your auto parts store, 3/4 inch size. Basically you are bypassing the front heater core that is connected to the firewall. You wont have any defroster and heater for the front, but the rear vents and control will have heat.
