The heater is located under the dash board to the right and down from the radio. To remove and replace it you will have to remove the dash board down to the fire wall. Also, you will have to disconnect two hoses that connect up to it from the engine compartment. These are located in the back of the engine and down on the firewall about midway. Once you remove the dash board and locate the heater core you will be able to see the location of these two hoses. Removing the heater core is time consuming but it will save you about 700 dollars.

SOURCE: Have no heat. Have replaced heater core,

I don't know your vehicle, but does it have a blower door tucked in where the heater core is? If it DOES and that's broken then it could be the whole problem. It would mean it isn't switching from the A/C side of things to the heat side of them. Hope this helps, good luck! Also, just looked up the proper name for what I'm talking about, it's called a "blend door" and I think your car has one. It's what I would check, again, good luck!
