My 01 had the same issue, and it was a leaking freeze plug. The leak was super minor, and some stop leak took care of it. I removed the upper radiator hose, dumped it in, ran it, and topped off the coolant level as needed. I thought it was a leaking heater box at first, but noticed the leak I thought I had was from the condensate drain from the AC system.
