I posted about this last year, I had a 2021 silverado LT and when the A/C compressor was on there was a humming noise, not the air blower but the compressor.
I then changed to a 2022 LTD Trail boss with the 2.7L turbo. No noise, very quiet.
I traded back to a 2022 LTD LT and same noise was present.
I now have a 2022 LTD LTZ and the same noise is here, is this a design flaw? Has any of you experienced this noise and most importantly have you been able to get rid of it without playing the dealership game? See video for reference.
