Why might the defroster-heater not be working on a 1997 Dodge Ram pickup?
If the air is blowing but not hot, you may be drawing in too much cold air while driving down the road. If that is the case, try blocking off a portion of your radiator with a cardboard box. Do not block all of it off as your vehicle may overheat. You might need to have the heater core flushed if its not blowing out hot air. If it its not blowing out anything try replacing the blower motor.
