Humming noise inside

[John Bendzsuk]

i hope someone can help me digure this out. 2016 Taboe LT and when i start driving it and come to a stop I get an annoying buzzing or humming sound. When i step on the gas it goes away. When i slow down you start to hear it again. Once i drive for a while it doesn’t do it anymore. I took video of the sound. The dealer says they dont hear when they take it out.

Video is too large to upload. I can send to anyone.

Any help or suggestions would be greatly appreciated

Did you turn off all ac/heat and see if it matters?

Is it a 4 wheel drive. There was a humming noise on some of those, maybe early production. A Google search may bring something up.

Yes

The chevy service tech told me its the a/c and thats normal to hear it buzzing. I think its BS cause i never hears ot before. Why would someone pay 50k to have a buzzing noise in the vehcile.

It don’t know the words, thats why it hums....

Try a sound clip so we can hear it. Kinda tough to tell you what we think without hearing the hum..

this sounds like the fan all ready went bad

Its not coming from the speaker.

Its not coming from the speaker.

Thats not a speaker, that the temp sensor (one of them) for the climate control. It has a little fan in there that will make a little noise when its going bad.

Hope you figure out where the noise is coming from

There is anther one in the back behind the rear passenger seat. It sounds like a air pump going on and off on my 08 Denali

I have a similar noise coming on my '17 LT, from under the passenger side dash and can also hear it under the hood. Dealer replaced the fan motor, then the A/C compressor with no fix. They then ordered a bracket for the A/C lines saying they were vibrating. Still did not fix it. They finally gave up and said if GM comes up with a fix they will call me. Been a year now. Still waiting for the phone to ring. Called GM and they just sent me back to the dealer. Oh, I did take it to another dealer and they decided it was lifters and then changed their mind and said it was injectors. They ended up claiming it is "not abnormal" and brushed me off. My last GM if they don't do something.

Not having any luck so far. Mine does it while in park and in 2wd. It almost sounds like the fuel pump but it's coming from the front axle area. Sounds like around the transfer case

Transfer case control module is the one I was referring to but only applies when putting the vehicle in 4 wheel drive. Does not sound like the issue you are describing.
