Why does the Corolla's air conditioning fan make so much noise?

Corolla's air conditioning fan makes a lot of noise because the car is shaking or the air conditioning outlet wind speed is too high. The following is an introduction to the Corolla: 1. Introduction: The Corolla, formerly known as the "Corolla", is a brand of Toyota Motor. The Corolla uses Michelin tires 215/45-R17 tires, TRD-Sportivo high-performance shock absorbers, TRD-TF4 17-inch sports wheels, reinforced clutches, and high-performance brake pads to ensure its ideal sports performance. 2. Space: The Corolla has also been lengthened in terms of body size. After lengthening, its wheelbase has reached 2700mm. In terms of seating space, a 177cm tall tester adjusts the front seat to the lowest position, with a fist of headroom. When the tester moves to the rear, there is 2 fingers of headroom and 1 fist and 3 fingers of legroom. The floor bulge in the middle position of the Corolla's rear row is very small.
As a long-time Corolla owner, I find the noisy air conditioning fan quite common, mostly due to blower issues. It could be thick dust buildup on the fan blades or small stones getting stuck, causing constant squeaking when rotating. Over time, bearing wear can also produce harsh noises. Another reason is a completely clogged cabin air filter - when airflow is blocked, the fan has to work harder, naturally increasing noise. I've solved this several times by simply cleaning the filter myself - easy and hassle-free. Alternatively, it might be aging fan motors or loose wiring, in which case a professional inspection is recommended. Overall, the Corolla's AC system is durable, but fan noise indicates it's time for maintenance. Don't delay, as repairs get more expensive if neglected. Regularly replacing filters prevents many issues.
I find the Corolla's AC fan noise really annoying, especially when blasting cold air in summer. Usually, the cause is a dirty cabin air filter clogged with leaves or debris, making the fan work harder and rattle loudly. Once, it turned out the fan motor was broken, producing a metallic screech due to prolonged wear. Wiring issues or foreign objects in the blower can also cause loud noises—I personally fixed this by vacuuming the air ducts with immediate results. On Corollas, such issues aren't uncommon. Addressing them early saves hassle; start with basic filter cleaning, then visit a shop if unresolved. Don’t ignore the noise—it harms comfort and drains battery over time.
I believe the noisy air conditioning fan in the Corolla poses a safety hazard as it can easily distract the driver. Possible causes include damaged fan blades, foreign objects stuck in the fan, or a clogged filter forcing the fan to operate at high speeds and produce noise. When encountering this issue while driving, the loud noise can be extremely unpleasant. I recommend immediately checking if the filter needs replacement. Long-term neglect may lead to motor burnout, increasing repair costs and harming the vehicle's overall health. While the Corolla's air conditioning system is generally reliable, fan noise indicates poor maintenance, which regular upkeep could prevent. Safety comes first—don't hesitate to have it inspected at a professional workshop.
