When the defrosters are on, even when you have the car on heat, the A/C compressor should be running. This is to help dry the air going through the heater. You may want to check this. Also, if the dealer did a heavy job of shampooing the carpet before you bought the car, moisture may still be trapped in the carpet pad. And, even though the carpet feels dry, it will take considerable time for the pad to dry. There are also drain holes in the bottom of the doors to allow rain to drain. If these drain holes are plugged water will puddle up inside the door(s) and could cause your problem. Hope this helps.
