I had the car for two years and this sound was not there. It is so noisy. I think the fan controler or heat sensor is defected. What do you think?

Before this fix, the AC was blowing cold air very fast, and now it takes more time (even with the noisy fan speed).

I will take appointment for a service at the dealer and will ask to check the car computer. I was told that this can be configured (I mean the fan speed).

Any more ideas please
