The front dash air vents do not blow air when in heat mode. The defrost vents work, the rear system also works. Using a combination of defrost, rear and heat to feet seems to heat the cabin okay. A/C works fine, new thermostat, pollen filters changed, no blockages observed. What could be causing this disruption in air flow?

Check all outlets to see if the system is not switching between them properly.
