Drive your car until it reaches operating temp, park it in your driveway and put the heat and blower on max close all the windows/doors. let it run for 30 minutes. this should kill all the bacteria that cause a bad/ moldy smell. turning off your a/c before you get home and always use recirc should also help. make sure there is no water leaking into your car from the drain. make sure carpet is not wet in the tunnel area near the drain. have seen some chargers with the drain improperly installed and leaking in the car.
