If its not water tracked in by your feet then you have some sort of leak. The heater core if bad can leak but it would smell sweet and have color to it.

Though, most grand ams are leak monsters, depending on the year/model it can leak in several places on the fire wall area. THe door gaskets, or if you have a sun roof they can leak if th edrains and gakstes are bad.

Hope that helps.
