My caravan has an odor of antifreeze in the passenger compartment when idling on 2008 Dodge Grand Caravan

I do not seen any signs of a leak inside or out. I do not see a decrease in coolant in the radiator

I suspect it may have the heater core in the early stage of failing. Another symtom I hear sometimes is that when the defroster is first turned on it may fog up on inside of windshield.
have cooling system pressure tested to determine cuase of leak. i also think poss hetaer core has a slight leak
