My heater was working last year but this year i turned the heater on and there's no heat. It blowing normal cold air. The engine temp is acurate. I know for sure that i need to charge my AC which I am aware of it. other than that no problems that i know of. Coolant was changed 3 months ago. What might be the cause?
