^^^ Yup, unless he is also stating that the first few notches or positions on the dial for the fan do not work as well. If they still blow while stopes then they work and you are just noticing this if not then a bad resistor or two.

when I drove that Chevy Cruze the Wisconsin and Illinois it was a almost 200 mile round trip. It annoys me that I was comfortable in the car but the air from the dash was too hot, then I turned it from heat to cold and then it got too cold the AC was off, but the vent position and temperature are not. There isn't a door that shuts air off completly from the
inside. Anyway I felt like goldilocks trying to find a comfortable setting.
