Hi. Hot coolant is pumped through the heater core. Heat from that coolant is then blown through the heater core and into the passenger compartment by the blower fan. Signs that your core is leaking include moisture on the passenger floor and/or slimy film on the windows. The heater core on your vehicle is buried inside the dash and is very difficult to get to. Replacing it calls for 8.9 hours of labor. This is not a job for a novice. I suggest you have a professional, like one from YourMechanic, inspect the coolant leak and determine what is causing the problem.
