This auto has Dual automatic Comfortemp heating system. When starting heat on cold days the blower comes on on high and continuies to run on the high speed. In the auto mode the blower should delay and cnd then blow out the floor outlet. Iyou can change the speed and transfer fromfloor to middie to winshield but no heat. Could this ba a bad temp sensor.
