The air conditioning in my Honda Civic 1.5 Sport makes an infuriating whistling noise. Have there been any similar complaints? Is there a cure?
Thanks in advance

It sounds as if it could be an issue with the actual fan that blows the air (both with and without air conditioning on) through the vents. Sometimes the blades of the fan can warp, or even melt slightly if you’ve been running the heat at full blast for a while (such as when defrosting the automobile on an icy day), and that can cause an odd harmonic effect in the airflow. Or, it’s also possible that leaves or some other sort of road debris has gotten in past the filter and is causing the whistling effect.
Either way, you need to get it looked at. It is possible to take the fan cover off and inspect it yourself at home (a Haynes manual is an invaluable aid here), but we’d always recommend asking a professional first.
