If the heater on a 1997 Maxima only blows warm to hot air when the engine is running at high RPMs what could be causing this?

I would check your anti-freeze level first and if its good i would proceed to changing your water pump & thermostat considering if I'm not mistaking its a 60k maintenance job and if that still fails it might be your heater core which is time consuming and expensive to change. (i have a little bit of knowledge towards this but I would check with a professional because I'm not one)
