Any accessory that is being driven by the engine increases fuel consumption. However, the overall situation is that modern cars are designed to be very aerodynamic and anything that alters the aerodynamics will also increase fuel consumption. This means that driving with the windows down will usually increase the fuel consumption more than running the air conditioner.
