2. Faulty Blower Motor: The blower motor is responsible for circulating air inside the vehicle. If the motor is malfunctioning or has failed, it won't be able to push enough air through the vents.
3. Debris or Obstruction: There may be debris or obstructions blocking the airflow through the vents. Check for leaves or other debris that could be caught in or near the vents.
4. Blend Door Actuator: The blend door actuator controls the direction of airflow in the vehicle's climate control system. If it's faulty, it may not be opening or closing properly, blocking the airflow to the proper vents.
5. Faulty Control Panel: The control panel (HVAC control module) is responsible for regulating the airflow, fan speed, and temperature in the vehicle. If the control panel is malfunctioning, it may not be sending the correct signals to the blower motor or blend door actuator.
6. Climate Control Mode: Ensure the climate control system is set to the correct mode (e.g., "Vent" or "Defrost") to direct airflow through the desired vents.
7. Cabin Air Filter: A clogged cabin air filter can restrict airflow. Check and replace it if necessary.
