If its a sweet smell you may have a heater core leak and the fan is blowing antifreeze thru the vents. If its a moldy rotten smell you have mold growing in your vents. This happens when the moisture does not drain properly causing mold. You can purchase a spray at most auto parts store to kill and stop this and refresh your air vent system.
