Why would the heater blow warmhot air while driving but cold air when sitting still?

Possibly defective thermostat. It sounds like it is opening up a bit with increased pressure caused by higher engine revs - when idling, the pressure decreases and the thermostat valve closes. Just a thought, anyway.

Why does your Dodge Ram 1500 blow cold air when sitting still and blows hot air while driving?
thermostat probably damaged or stuck....and worse case scenario....your heater core is going out.
Why will a car not blow hot air when sitting still only when driving?
On some cars this is because of the heater circuit design, in that if there is air in the cooling system it can gather in the heater core when at idle, and allow substantially less, if any, heat exchange. When the engine RPM goes up, as when driving, the air gets forced out of the heater core by the fast moving coolant and you have heat again. If this is your problem the solution is to bleed the cooling system on that vehicle, per manufacturer's instructions.

I would expect a plugged heater core.Take your hand and feel the two heater hoses that pass thru the firewall on the passenger side; if one is hot and the other is much cooler, than you heater core is plugged and needs replacement.
