It was winter in Chicago when I bought it, so I needed major heat. I would turn the heat up all the way to the last setting to blow on the floor. (The floor because the heat circulates better from the floor in other cars). My passenger would be warm and toasty, but my toes were still hanging on for life. I took it in to get it fixed and was told it was "fixed". I beg to differ, but didn't have time to keep taking it in.
