I noticed this humming / buzzing noise today. I normally always have music or something playing however today I did not. I was driving around with the A/C on and noticed a noise. Is this buzzing / humming normal? I don’t want to make an apt at the dealership and look like a dingus if it’s normal. It gets more noticeable the harder the fan has to work. Lower fan level lower the noises.

Thanks in advance.
