I have a 2003 Nissan Pathfinder SE w/ 3.5L. I have the digital A/C. The A/C or Heat only has air flow from the vents when the car is moving. The temp works fine when adjusted. But all air flow stops when the car slows or stops. I do not hear any fan going on or off at any time. The controls ( temp adj., air flow direction etc) work except for the fan speed. On the read out it shows the fan at different speeds but there is no air movement unless car is moving.
Could this be the blower motor or resistor or both.

Thanks
