I believe your heater core is connected to the inlet and outlet tubes (that pass through the firewall) via some clamps and O-rings. It sounds like an O-ring is leaking through. It could also be the heater core leaking. On these newer vehicles, the heater core can be replaced without removing the entire dashboard, however, the job is still not real easy on your vehicle because of a few things that have to be removed from under the dash, and the tight working conditions in that area.

 

You have a leak in your hvac heat exchanger coil that is internal to the blower assembly under your dash. You will need to get it replaced.
