Air conditioning problem in a Renault Megane

Hello, I have a 2016 Renault Megane with a diesel engine and 200,000 kilometers. I'm having a problem with insufficient cooling/heating and fan operation. When the air conditioning is running, it starts correctly, but after about half an hour the fan power decreases and a noise is heard as if something is inside. My workshop mentioned that the inlet to the air ducts is closing. Has anyone experienced a similar problem or has any idea what might be happening?

Summary of the thread

A 2016 Renault Megane is experiencing issues with insufficient cooling/heating and fan operation, where the fan power decreases and a noise is heard after about half an hour of air conditioning use. The workshop suggested that the inlet to the air ducts might be closing. A possible cause could be a clogged or dirty cabin air filter, which can restrict airflow and cause the fan to work harder, leading to noise and reduced performance. Replacing the cabin air filter is recommended as a potential solution.

Check if the cabin air filter is clogged or dirty, as this can restrict airflow and cause the fan to work harder, leading to noise and reduced performance. Replace it if necessary. Let me know if this resolves the issue or if you need further assistance.
