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.
Climate control not blowing air — blend door or blower motor?
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.
