Jeep Commander was created in 2006.
The heater core is inside the hvac housing behind the dash.
I also have a 2000 jeep wrangler. This year has a problem with the heater core plugging up. You can either try to flush it out, or just replace the heater core.

To replace the dashboard heater control bulbs on a 2006 Jeep Commander, first, disconnect the negative battery cable to ensure safety. Then, remove the center console trim and the screws securing the heater control unit. Gently pull out the unit and locate the bulbs; twist them out and replace with new ones. Finally, reassemble everything by reversing the disassembly steps and reconnect the battery.
