Heater Blower Motor Resistor. If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or aswitch or resistor that controls fan speed isn't working. Another cause might be that the electronically controlled “blend doors” that direct air flow are stuck or broken.
Why does my heat only work when the car is moving? When your vehicle is in motion and driving down the road, then engine coolant temperature tends to get hotter on the engine before it gets to the radiator, so the heater will naturally heat up more when driving around. First check the engine coolant to make sure that its full. Top off thecoolant if its low.
