AI4Car quick readA short, original guide from the AI4Car knowledge library.
If you notice a rattle from the cabin blower, capture the exact conditions instead of relying on “it happens sometimes.” Note fan speed and whether the sound stops when the fan is off. Save the date, mileage, and any warning message.
Repeatable notes help a technician reproduce the concern and distinguish a one-off event from a pattern. Check the cabin filter and visible intake area with the car off; leaves can collect near the blower.
