Driving naked? :-) It's not delivering 28C air as far as I can tell. As I said, there is almost no change in delivered air temp between ACC settings of 70F and 82F. If I'm not warm enough at 70F, then the 82F setting is no better. Then one more notch to HI and suddenly the delivered air temp jumps something like 20-30degF or more. > Perhaps Saab assumes people have winter clothes on when driving in > winter temperatures? Ha ha. I don't care if I'm wearing twelve sets of thermal underwear, that has no impact on the delivered air temp. And the delivered air temp does not increase substantially as you increase the ACC temp. Which means you have poor control of the cabin temperature, and it takes a long time to warm the car. As it happens, I have very poor circulation to my hands. Wearing gloves doesn't help, because (unless it's *really* cold outside) gloves and other forms of insulation only work to hold body heat IN. If my hands are icy cold, gloves only serve to keep OUT the heat in the car. So I want warm air coming out of the vents to warm my hands. I hold my hands (usually one at a time :-) in front of the vent to thaw them out. At 82F the air is still uncomfortably cool. One click higher at HI and it almost burns my hands. I don't consider that to be very good control. My 9000 worked exactly the same way. I prefer a simple manual-control heating system so I can make it do what *I* want. Gary
