Yes it's the heater core, It's a complicated diy job and unless you are an experienced mechanic you are going to need a good workshop manual for the job.
Best of luck.

Sounds like your heater core is bad. Have someone check out the heating system and possibly replace heater core.. that should take care of the fog problem also by enabling you to use the defrost... Good Luck!

SOURCE: Heater core or blower motor?
Sounds like your blower motor , you heater core is a non mechanical part and if it were the issue you are correct in thinking you would see fluid on the floor or mist on the windshield.

I am going to assume that you checked to make sure the cooling system is full. The next thing to do is flush out the heater core. The easy way to do this is to clamp off the heater hoses with visegrips and remove them from the heater core. You will only loose the coolant that is in the core this way. Take a garden hose and try to backflush the core out until the water is clear. Being that you said you don't feel the inlet hose getting warm the chances are the core is completely blocked so it may take some working back and forth between inlet and outlet to dislodge anything in it. I have also had to use an air compressor to do it but you need to be very careful not to use too much pressure or you can rupture the heater core. Worst case is you will have to replace the core but I would try flushing it first. Hope this helps.
