It does require removal of some of the dash to gain access.. When you put your finger on the wet spot does it feel slightly smooth/slippery, like a bit of oil and/or is it pink colored? Does it smell sweet? don't taste it to see, if it is coolant it is poisonous.
I tried to find a you tube video that would explain how to do it but there were no good ones. I did learn though that it would entail taking apart the dash and that your heater core sits directly above the front center of your passenger side foot area beneath the dash
