When I turn on the heat, it only blows hot air when I'm driving. If I'm not moving I don't feel heat coming out of the vents, so I know the heater core is fine. How can determine it is the blower motor or a resistor? I don't know much about this so any input would be great. If anyone knows of any writeups done on diagnosing this that would be great too. Thanks.
