My 2003 Sable has auto climate control. It's not blowing heat, even when you run the temperature up to 90 degrees. I haven't checked the heater hoses to see if one or both are hot, but if they are, would it be a blend door motor or some electronic glich in the climate control system? Also, engine temp is in the normal range.
