When driving at around 100 km/h or above, I hear a wind noise coming from the driver's side window. The faster I go, the louder the noise gets. I've tried both with the air conditioning off and with internal and external circulation, but the noise is still there. It sounds like the window isn't fully closed and is letting in air. What's going on?

When driving above 80 km/h, there's a noticeable noise near the passenger side A-pillar. At higher speeds, like 120 km/h, the noise becomes even louder.

Has anyone replaced the door seals? How's the effect? The wind noise is getting louder.

Hi everyone, I've got an '07 model practice car. When I turn on the internal circulation switch, the light comes on, but there's no circulation effect. What's going on?

If the external circulation of your car's air conditioning system can't switch to internal circulation, it might be due to a problem with the actuator or a control switch. The cost for repair can vary depending on the make and model of the car and the specific issue. I recommend consulting a local mechanic for an accurate diagnosis and cost estimate.

I want to ask the experts, why does the air conditioning not work when I turn on the internal circulation? The light comes on briefly and then goes off, but the heating works fine. Why is that?

For a 2013 Suzuki Swift, if you're experiencing a buzzing noise at speeds of 40 km/h and above, and the noise gets louder as you go faster, what can you do to reduce the sound? Any advice from experts would be greatly appreciated. Thank you!

Hey everyone, I've got a question. With my 2017 Honda City, when the windows are open while driving at 100 km/h, there's wind noise coming in. What could be the issue?

Hey everyone, the AC isn't blowing any air, and there's no air coming out on internal circulation, only natural airflow. Have you encountered this before? Is it the blower that's broken? I saw online that there could be many reasons. Is it necessary to replace the blower with an original one?

When driving at 80 mph, the wind noise is really loud, almost like air is being forced in. Do you guys experience this with your cars?

Is it possible to set the car to default to internal circulation instead of external circulation when starting?
