A windshield having an upper vision area with a coating and a lower heating area aligned with a wiper blade storage area. When the coating is electroconductive, first and second bus bars are provided to selectively connect the coating to the terminals of a power source to provide a windshield heating circuit for defogging or defrosting its vision area. One of the bus bars is also connected to a heating element along a lower area of the windshield that faces a storage area for windshield wipers. The heating element is selectively connected to a different terminal of the power source from the terminal connected to one of the bus bars to cooperate with one of the bus bars and the power source to provide a storage area heating circuit. The windshield heating circuit and the storage area heating circuit may be operated independently, either separately or simultaneously, from a common electric power source.
