First what year of car, and what does it smell like? Some vehicles have a recirculation filter behind the glove box. Or the floor mat could have something on them that make the odor. Try running the a/c on low and not on max. max recirculates the air in the cabin so any odors in the cabin stays in the evaporator when it collects water on it. In high humidity the evaporators can build up with mold and cause odors.

Is the smell the same one you smell after a rain? If so, read this:
