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??
Okay, so I've searched as best I could and didn't come across a topic on this. Apologies if I missed something. My '14 Silverado 5.3 has 28,000 miles on it now (got it at 26,000) and since then there has been a strange humming or whining noise coming from what I deduce must be the torque converter. It can be heard in park when revving and in drive under acceleration or just cruising a parking lot, most noticeably in the lower RPM range in all cases. I wish I had noticed this at the dealership, but I was not paying attention. The noise is worse at times, but always present. This is clearly an issue, I mean the thing sounds like a 15 year old Trailblazer whining around a parking lot and that's pretty unacceptable for such a new vehicle. I only plan on keeping this truck for a year or so and stepping up to a '16 or '17 Silverado/Sierra when finances allow (see my novel of a intro in the new member forums...), but its still a nice truck and I want it to act and sound like it should. Has anyone else had TC or Trans issues on their 6 speed trucks? Is the dealer going to give me the "normal operating conditions" line of bs? Thanks y'all. -Max
