  1. Tried the upgrade obviously before reading this post. 2 issues; switch does not function and was extremely hard to plug in, I assume it was the wrong one? Pulled a switch from my buddy’s 2018 and everything functioned except passenger mirror will not unfold or fold for that matter. Pulled a ton of fuses didn’t find a blown one. Which one would it be? Power window still works on passenger side figured it was that one but apparent not. Plugged my old switch in and functions except obviously no fold feature? Sorry to bug but I’m in desperate need of help
  2. Yeah that would probably be the best solution, I have always liked the fact that the G80 did the "locking" for you over having to disseminate whether you should lock up or unlock now because you may not need it,etc. I have owned 6 GM trucks, all had G80's for the exception of one, my first, a 1972 K10 short box with a "limited slip" option, using the same principle. Loved them all except my 2015 because it does not allow itself to lock without turning the traction control off, may has well be like the Ford or the Ram, you have to "activate" it now, and it's totally not an "automatic" locking rear differential any more. I realized this long ago when I bought the truck in 14' just griping about it now. Yeah, and I kick myself every day that goes by that I sold my 72 K10. I sold it to my little brother who was turning 16 (I was only 19 myself), he still has it to this day, and will not let it go. I upgraded to an 88' 1500 4x4 short box with the G80, it was a 4 wheeling motha!
  3. So I pulled out of the driveway yesterday and we had a little bit of frozen rain over night, yea I know Colorado weather is ever-changing. Any way, I started out on a patch of ice, under one rear tire only. Before the spinning tire produced enough centrifugal force to engage the G80 clutches, the traction control engaged the rear brakes on that particular wheel, basically stalling the truck out by fighting brake force against engine torque. Question: So the G80 locker design is to overcome the one wheel spinning open differential age-old problem and provide traction to both wheels and get you off of the ice correct? If traction control does not allow the spinning wheel to reach the proper RPM to engage the locker, what is the point? I can't imagine trying to climb a hill or slog through heavy mud and snow in four wheel drive and have this act up. I realize you can disable it, and the stability control re enables on it's own, and causes other issues, I have tried to just "tear" through the snow in 4 wheel drive and all of the "safety" enhancements really just drown out that fact that these are still designed for some off road capabilities. Also, being and engineer I realize that these safety feature, while not fun do serve a purpose, most of the time. Back to my question, is there really any value to the G80 anymore while traction control is enabled?
  4. All four of my windows roll down upon holding the unlock button, without changing any settings. With that said my truck is a 2015 (not 2015i) that came equipped with the carryover camper style mirrors that do not have the power fold option. I hate the mirrors, my biggest regret is not waiting a month and getting the power fold, spotlight, chrome capped mirrors. I have searched this forum high and low to see if I can convert and it seems I'm stuck with the old style. Hope this helps.
  5. Awe man that is a real bummer, if I could not get the power fold option to work it's not worth it. Thanks for all of your help!
  6. Wow, quite the undertaking it seems. I really like the mirrors and it buds the crap out of me that I have the 9 year old carry-overs and most everyone else does not. I'm sure I am mechanically capable of doing it but I really wanted to have the power fold option. I thought that if the door switch was purchased and the BCM was flashed that function was able to become available? It almost sounds like a trade in is about as expensive.
  7. Yes and yes, when I ordered it the other mirrors were not even available yet. They were carryovers from the previous generation trucks. Power, heat, and turn signals only
  8. I have searched high and low for the topic that listed out all of the parts, and necessary upgrades to change from my mirrors in sig to power folding, LED, spotlight, blah blah blah mirrors. Can someone direct me there or help me out. I have been looking on ebay and cannot get clear answers. Some vendors say if you have RPO code K40 for diesel engine brake there is a temp sensor in the right mirror and the swap will not work? Sorry to bring this old topic up again
  9. Does anyone know if I can even convert to the DQS mirrors? My 2015 is pre 2015I, so my mirrors are the old carry-overs. I don't know if I can even get a BCM flash to control the new ones (power fold, led's backup led's). If it's possible, is it even worth it?
  10. Tires are the answer for sure. I've done mild fourwheeling in mud and snow and I find a couple things particularly annoying. If you do not disable traction control, and have the G80 rear end, it's pointless. The diff will never lock up and when your trying to hammer on it up a hill the brakes are trying to stop the tires from spinning. Also if you get into deep ruts and have it disable where you are capable of making the tires spin, the stabilitrak is activating, and it's impossible to keep off. GM just needs a 4x4 override button to disable these features so the experienced human 4 wheeler can take over.
  11. I optioned my SLT out with every option a Denali is capable of having. The only thing less is the configurable instrument cluster. Minor trim on the seats, which actually the SLT's look richer. They do not have the cloth bands and edge bead. I wanted a Denali with chrome bumpers, and monochrome was the only option, that is why I opted for the SLT.
  12. My tires no not Firestone, they are Goodyear. Tire brand or size does not make a difference, it's internal to the front CV Joint assembly or outer differential bearing assembly. Until there is a legitimate TSB, I think we are all stuck with it. I have had numerous people drive it and experience the same noise, hum that I do. You cannot hear it from the driver's side. The funny thing is, the only people on the planet Earth that cannot hear it by driving are GM Techs. Go figure.
  13. So have I, this is my 4th GM 2500 Duramax, and this is the loudest (road noise), by far!
  14. I checked the boot you are describing and it seems to be intact. I will take a closer look this weekend when I have daylight. Thanks for the tip though.
  15. Nope does not "buffet" at all, it's road noise coming from beneath the from left wheel well.
