I have a 2010 Legacy with All-weather package. When i engage the one button for the heated side mirrors , rear window and front wiper de-icer, the side and back do get hot, nothing in the front under the wiper blades. Went to dealer today, they tried the same with a new , 2011 Legacy, again only the side mirrors and the rear window heated up, not the area under the blades. Is this a unknow defect in all 2010/2011 Legacys?
