I was driving home from work on a rainy night and turned on the front defroster. The defroster would turn on at full blast and make the inside of the car really warm, so I turned it off. A few minutes later the windshield would fog up again and I'd have to turn the defroster on, then off since it would get really warm inside, and the whole cycle repeated. I tried playing with the temperature/vent/AC settings but could not find one that would leave the defroster on low so I can leave it on throughout my commute. Am I missing something or can anyone help me find an optimal way to use the defroster for an extended period of time? Thanks.
