The problem with humidity is that it can come from multiple sources. The air, obviously, but we create humidity, our breath. Our wet shoes and clothes that wet the floor mats and seats create humidity. So, even in winter I would leave the AC on and turn up the heat a bit. Moisture from the wet floor mats and seats (and jackets and gloves etc) you leave behind when you leave your car evaporate into the air and now you have a humid condition with no circulation. If you turn off your AC even a few minutes before you stop the car, you will introduce relatively more humid air from the environment into the system (ducts). When you turn off the car, the evaporation from wet surfaces will ADD to the humidity. On the other hand, if you leave your AC on, your relative humidity will be
lower than if you hadn't. So the overall humidity from evaporation will be
less with less of a chance for mold and mildew.
Another great tip is to not leave wet clothes in the car and use weather proof mats that you can wipe down when you leave the car.
