Driving along in the bitter cold, maybe once a week, I'll notice I'm freezing my butt off. Well, heated seats but my legs are freezing! Bend down and ice cold air coming out the floor vent. Look up and temp is at the top, max (80 I think). I never move the lever from max heat in the winter. To get heat, I have to lever down to 60 then back up. Boom heat again. You think sticky "blend door", or a programming thing. Live with it? Other? Thanks much!
