Hi there, Mia!
It seems like the issue with your 2014 Subaru BRZ could be related to the air distribution system, possibly the blend door actuator. The symptoms you've described, such as the air only blowing through the main vents and the sound of a clicking noise, are commonly associated with a faulty blend door actuator. While diagnosing this without professional help can be challenging, you can try the following steps:
- Check the Blend Door Actuator: The clicking sound you hear could indicate a malfunctioning blend door actuator. You can try locating the actuator under the dashboard and observing its movement while adjusting the vent modes. If it's not moving properly, it may need to be replaced.
- Inspect for Obstructions: Ensure no obstructions are blocking the vent openings or the blend door's movement.
- Diagnostic Tool: Using a diagnostic tool that can interface with your car's HVAC system may provide more detailed information about the issue.
While some of these diagnostics can be done at home, considering the complexity of the HVAC system and the possibility of multiple issues, it's best to consult a qualified mechanic. They have the experience and tools to accurately diagnose the problem and recommend the appropriate repairs.
Remember, addressing these issues early on can help prevent further damage and costly repairs down the line.
