AC and heat blowing fine but very little air coming out. Or air stuck in one direction. This fault code is stored when the engine control unit detects a specific fault condition. Common causes include sensor failures, wiring faults, and component wear. Always read additional fault codes before replacing parts — multiple codes together provide a clearer diagnosis. Clear the code after repair and test drive to confirm the fault does not return.

HVAC airflow issues: 1) Very low airflow from all vents: blower motor failing (brushes worn) or blower motor resistor. Test: does fan speed control still work? If only high speed works = resistor failed (common, cheap fix $20-50). If no speed works = motor or fuse. 2) Air stuck in one position (floor only or defrost only): mode door actuator motor failed. Listen for clicking from dashboard when changing modes. 3) Temperature stuck hot or cold: temperature blend door actuator. Actuator motors: $20-80, may require dash disassembly for access.
