  1. Why does my heater not gradually increase as I raise the temperature ?

you mean the air doesn't get hotter when you turn up your temperature dial?

2. Why does my AC not gradually increase as I raise the temperature?

what does this mean "increasing AC"? Do you mean the same thing again? ... the air doesn't get hotter?

 

Are the heater core hoses hot? Coolant level OK?
