Coolant leak when heater is on

I have a 2002 Blazer 4 door 4.3 and just noticed today that when my heater is on, coolant leaks. I cant see where the leak is coming from. The smell is only on the outside and the cab inside on the floor is not wet. Any suggestions?

Are you sure that it leaks only when the heater is on? Coolant is always flowing through the heater core, so inside heat or not...
