Of course these cars have heater cores. How else would you get heat in the cabin? THe heater core is buried inside the dash in front of the radio.

If the heater core is leaking, you should see antifreeze leaking from the AC drains hoses. But I see no correlation between smelling coolant and the fan not working.

Was the fuse burned out or was it just not making a good connection like frequently happens with this type of fuse?
