Coming up to my first winter with my '03 Aero. Have had a few chilly nights where nothing was required but the rear defrost, but it appears I have to have the ACC on and some form of air blowing up front just to activate the rear window defroster. Kind of annoying. Am I right here, or is there a work-around? Every car I have had in the past had the rear defrost separate from having to activate any other climate controls.
