Has anyone experienced a similar issue? I have a 2019 Silverado trail boss and when you turn the fan on, whether it’s ac or heater, there is a noise that is not normal. It comes from the passenger side inside the dash area. It’s not a loud noise and if the stereo is on you won’t hear it. It sounds like the fan motor is off. 

I wouldn’t bother taking it in if all trucks made the noise but they don’t. I had the dealership take me in another trail boss and there was no sound, just normal wind sound. 

They changed a bearing saying that was the issue but it is still making the same noise. The second time I brought it in they said they are reporting it to GM. I brought it in today and the service desk worker said it’s “normal”. I asked why the others don’t make the noise and he said it’s “normal”. Obviously not normal or they would all make the same sound.

 

Anyone know what it is??

I know this is an older post but i was wondering if you were ever able to get it resolved?  I took my 2019 in today due to hearing this constant white noise type buzzing coming from under the dash near the glove box.  They also told me it was "normal" because they had another vehicle doing the same thing and they replaced the AC unit and it did not stop.  It drives me insane when I'm driving because I cant unhear it now.

Haha yea that’s the noise! So since that post I actually traded my 1500 in for a 2500. But while I had the 1500 I was able to resolve it almost completely. So if you go back to the dealership check to see the ltz or high country models. Look under their glove box. You’ll notice that the higher trim models have a padded insulation cover over them. I had to order one which costs about 30 bucks. Put that cover on and problem should be solved!

      So around this time of year last year I changed my brakes and my rotors and was going to replace my front bearings as well. My 08 is a Michigan truck so it’s got a plethora of rust accumulated. One of caliper bolts had seized so I completed what I could with the brakes and headed home to figure the best attack for a seized rusted bolt with thread lock. Anyways that bolt was a ******, so I went to my brother cause he had an air compressor and thought we’d try that. Needless to say the bolt one, so my brother put the wheel back together but before he put the caliper back in place over the rotor he decided to decompress the spring?. Why? I have zero idea thought it was pointless for him to do that Considering I had to do it to change the springs. So I start to head back home just worried about getting this bolt out so I can change my bearing. So as I start to leave I don’t notice anything out of place until I get down the road and my brake pedal goes to the floor. It made no sense, I couldn’t figure out what happened in the 30 minutes I was there; that would take my brakes from having good pressure to having none.  Then not long after that my fuel pump goes. Old Murphy’s law coming in clutch for me! So I get the fuel pump swapped get the caliper freed so I could replace my bearing. Then go to bleed my brakes and I can’t get any of my brake pedal back. I have abs so I I went out and bought a scan tool cause I heard bleeding brakes with an abs system without the scan tool is difficult and is more than likely the reason my brakes still go to the floor. So I do everything the device tells me to. There’s no change, except now I can’t shift it out of park to even attempt to check if there’s at least some pressure. I’ve been battling these brakes so at least the last half of 2021 my family is telling me to just sell it for whatever. Honestly I don’t want to sell it I rather enjoy having it and am not ready to let it go. Any help or advice would be so appreciated!

      I have a 2017 Silverado 5.3L. Used to stay around 40 pounds of oil. Now when idling, is goes down to 20-25 ish pounds. It’s not throwing any codes up but does have a bit of a knock if I floor it without letting the pressure build back up first. Cold start it’s just below 40 pounds but at operating temps (210) it drops like crazy. It’s not oil quality or level, I just changed it last week and it was good for half a day and went back down.

      My 2019 trailboss has a rattling noise coming from the engine I hear it over the exhaust. (aftermarket) I don't hear it inside cabin. I only hear it outside also with the windows down. Dealership said its normal but it sounds terrible. Anything I can do??

      A question here.
      I put my winter tires and wheels fromy 2019 Silverado 2500HD onto my new 2021 Silverado 3500HD  and the truck will not read the TPMS sensors. The tire shop said the dealer needs to reprogram the sensors to the new truck. Took it to the dealer and they say that this cannot be done even though the TPMS part numbers are identical between the years and that I need to buy new sensors for the new truck. Any help would be appreciated as this makes no srnse to me! Thanks in advance.
