I was considering trading my 2016 Sierra 1500 on a new 2019 Sierra but after seeing them in person I think I will keep mine. They look nice but did not change enough to make me want one especial the interior. My truck is black with Cocoa Dune interior all the 2019 have to offer is jet black or dark walnut. Think I will wait a while and see if GM will upgrade the interior. After all of the hype and anticipation over the last few months I have to admit I was disappointed.
Harold Rutherford replied to Gorehamj's topic in The NewsroomI went to look at new 2019 GMC Sierra thinking about trading my 2016 Sierra they are nice but not enough interior improvement to make me want to upgrade, I also have Cocoa-Dune interior and all I can find are very dark color interiors. maybe next year they will make interior nicer. I also looked at Ford F150 and Ram much better looking inside where I have to be. Think I will wait for a while and see what GMC comes up with. .
My fan on recirculate is loud but on auto quickly goes to outside air and is now quite maybe because mine is a pick up truck and requires a smaller fan than the SUV's. Thanks to you I love my truck again, I had a friend ride with me today that owns a 2014 Toyota Tundra and he was shocked on how much quieter it is now. He used to harass me for buying a GM truck until his had to go to shop with a smoking engine with 40K now I am doing the harassing. lol
Update on A/C noise 3 weeks after installing the duct seal around lines (see pictures above) outside where the lines enter the firewall the noise has disappeared, gone, quiet. I never realized the noise at low speeds was also there at any speed because now the Truck is much quieter all the time! Finally I love my Sierra and would like to thank Jim again for the simple common sense fix. I hope GM reads these post so they can save others from total brain damage from the noise from their poorly designed A/C systems, not to mention my 5 service trips, unnecessary new compressor, new fan motor and rental cars they could have fixed it for less than $7 and probably saved hundreds or thousands of customers.
My 2016 GMC Sierra 1500 has had a loud noise inside cabin and GMC service has tried everything to fix it, they new compressor and fan motor none helped. It has been in 5 times for repair but no one could figure it out. Finally on another post I saw a fix so I tried it and so far it has eliminated the noise. Cover the incoming metal lines outside under the hood with 1 lb bar of Duct Sealer (found it at Home Depot in electrical dept) form it around metal housing and tubes where lines enter firewall takes only a few Minutes to do. After 2 years of agony I could not believe that it stopped the sounds but it did. I will attach pictures of solution good luck!
Thank you Jim, I tried the duct sealer bar from Home Depot as you suggested and so far it has stopped the AC noise in the cab. I can't believe GM can not figure this out but you did, you're a GENIUS! Maybe GM will give you a job fixing their un-fixables lol I will attach the pictures of my fix because it is different set up from your pictures but thanks again for the suggestion and solution to the most annoying noise.
I will get some of this putty and try it, what do I have to lose except the cost of the putty. If this works GM should do this under warranty and save their customers from going berserk! I have returned 5 times for this problem maybe you have solved it for me. Thanks (praying for good results)
Jim, the last technician did get in the truck with me and he did acknowledge the noise he actually rerouted the line going into the firewall away from all metal and it helped somewhat. I will give them credit they have done everything they can to stop noise from changing the compressor, fan motor and rerouting AC lines it has reduced the noise level to almost acceptable. I think GM should get on this problem and fix it and stop denying there is a problem I have purchased 7 brand new Sierras first one to give me any problems. I still love my truck other than this annoying AC noise. Keep hoping for a solution soon. If and when they figure it out I hope they will man up and recall these trucks.
I did get in the truck with the tech and service writer, they hear the noise but can't pin point it to fix it, hopefully GM will figure out the problem and come up with a solution in the future. If anyone can figure it out maybe they will post it and I can pass it on to the Tech. My 2014 Sierra had dim lights after 2 years they changed them out to a new brighter lights that was much much better so there is still hope.
Update on AC noise: I got my truck back from the dealer today (4th time in for noise) they had it 4 days and stated they could not duplicate noise so I assume it is un-fixable just have to keep the radio blasting when not on highway. It's a shame because other than this very annoying noise I love my truck.

As the weather warms I have noticed the A/C noise is getting loud again almost as loud as before the new compressor and fan motor, this is driving me crazy! I have purchased 7 new Sierras and this 2016 is a first for A/C noise. Too bad because I love the truck but really starting to change my opinion, whats worst is no one knows how to fix it. GM needs to buy these back if they can't be repaired.
I recently had the dealer install the GM Cold Air Intake on my 2016 Sierra 5.3 V8 and I have noticed a lot of power increase as well as +2 miles per gal fuel millage the only down side is the deep throated sound when accelerating not noticeable under normal driving. This video may help you decide it was the one I watched that helped me make up my mind. Good luck! https://www.youtube.com/watch?v=ryyqwT28Ua4
