Antifreeze leak...

First off, wanted to say a much deserved thanks to the members who helped me diagnose my bad hei control module. Now on to my next problem. Antifreeze leaks out of the bottom of my a/c box(heater box mounted to firewall) when the motor gets to operating temperature. It leaks for a while, then stops(basically stops when the motor cools off after shut down). Today, I noticed smoke coming through the inside heater vents and it smelled like antifreeze, so I'm guessing it has something to do with my leak. Any ideas on what is bad/leaking? I'm guessing heater core, but I don't feel like tearing that a/c box off unless I have to. thanks
