I have the 3.0L Duramax diesel, and on random cold starts there is a buzzing coming from behind the dash. Haven’t been able to find where, sounds like two plastic pieces vibrating against each other. Anyone have happen to them? Tough since it doesn’t do it consistently. Attached a video of the sound. 4b67c43a-b3fd-46f3-b834-e703b37aad0a_compressed.mp4

I am having problems with my air conditioning again. My A/C is blowing warm air and this is the second time I have had this problem since buying my 2015 Sierra less than 6 months ago. A few months ago I had the exact same problem and my dealership diagnosed it as a leaking hose and all of the freon was gone. They had to order a new hose and it took a week for it to come in. They installed the new hose and added more freon and it has been fine for the past 3 months until today. This morning I noticed that the air coming out was warmer than normal even though I have the A/C set at 65 degrees. It was fine yesterday. I am going to monitor it and see if it gets worse and if so make an appointment to take it to the dealer again. Just wondering if anyone else has had to replace the hose or had a freon issue with their 2014 or 2015 Sierra / Silverado?

My 2016 Sierra 2500HD has 176,000 miles on it already and recently started eating parts. The latest part to fail was the reductant tank heater (DEF Heater). Upon cold start the check engine light came on with code P21DD. After a little reading I learned that this can result in “Limp Mode”. I was in the middle of nowhere in Northern Wyoming. Not cool! I drove down to Denver and replaced it that week. I shot this video of the repair..... -
Hi all, Long time lurker who finally created an account. Y'all have been a wealth of info and I really appreciate it. I have a 2001 Tahoe LT Autoride with the 5.3. My father-in-law bought it new and I bought it from him when he upgraded to a 2019 Tahoe Premier. I've been going through the Tahoe since buying it from him. It was always maintained at the dealer and serviced at every interval. The issue I am having now is a hard start when cold. It takes at least 2 cranks to get it started in the morning or after a long period of not driving. I have searched the forums and found some help but no threads with results. Here is what I have done so far to remedy the issue. -New plugs -New fuel filter -New fuel pump -Techron in tank (one bottle so far) I have a new fuel pressure regulator coming and will swap that next but the telltale signs of failure aren't there (gas leaking through vacuum line). The truck had one other issue that has since been fixed. It would overheat (on the gauge) on hot days mainly at low speeds and belch coolant when turned off. I ended up replacing the fan clutch, coolant temp sensor, expansion tank, thermostat, and expansion tank cap. Any advice would be hugely appreciated! Thanks all! -
2015 chevy 1500.. 3400 miles. A couple of times the heat didn't work. It always did "next time".. the other day I had to take a 3 hour drive.. it didn't work the whole way there...stopped for an hour..headed back still with no heat (it was 42* so it was not pleasant) Took to dealer - they said they cant find anything wrong, of course, and of course the he was working fine. Its only done this a couple of times in the past 2 months now. Anyone experienced anything similar? It blows out air, and it will adjust the fan speed properly (or what I'm guessing WOULD be properly if it was blowing out heat) based on the temp of the cab. Even when taken off of auto and just turned temp to hi and fan speed up, with AC button off, it was still blowing cold air. Any ideas? Could it somehow be user error? (doubtful) Also when the AC button is on, even when its on heat, is the AC really still running? seems dumb that lights always on even when you have the temp high and its blowing heat.
