Won't put out hot air. Sitting still its cool air and just warm on the highway. It's getting up to full temp on the temp guage. Lower and upper rad hoses just changed and all new antifreeze. Heater core is not leaking.

Check to see if the coolant is full. Also, check if both heater core hoses are hot. It could be plugged.
