  1. Seems like the majority, if not all are the drivers side.
  2. My Sierras DLR lights match when I first start the truck then after a few minutes the driver side top turn a lite blue. I went and checked and mine behaves the same way with headlights on, clears up, off back to blue. Thanks for pointing this out.
  3. My 3 month old 21 Sierra SLT has developed this problem on the drivers side but its intermittent, usually when I first start it its white like the other side then will change to a lite blue and pretty noticeable. Of course took it the dealer and it stayed white! Lol Has anyone else had theirs act this way? Will it eventually stay blue?
  4. Is the ASE module causing the rough shifts or is this an existing condition before installation? Looking to get an ASE for my 21 Sierra, but holding off until I get more info on this.
  5. I think that spare plugs for the power sunroof.
  6. My Sierra SLT 6.2 /10 spd was built the week of 3/22 and a delivery date of 4/22. It now has a delivery date of 5/9. As far as I can tell its still bayed at the plant in Silao. My Dealer thinks its being held because of the chip issue and to check on it next week.
  7. After more research and checking with a GMC parts dept. the 84487008 comes as spoiler only now. The 84515395 is the High Mount Lamp with Camera only, no spoiler. I need to double check to make sure its for the mirror and not the bed view, the description just states rear camera. This comes with no harness, so will need 84479945. To summarize the parts needed for the mod. Mirror 13536995 Coax 84335461 High Mount Lamp 84515395 Harness 84479945 Thanks for the for the help Hiyo!
  8. Hiyo, Thanks for the reply! I already have the Mirror and Coax on order from Gmpartsdirect, Its the camera and harness part numbers that I need. From what I understand 84487008 does not/no longer includes the harness from reading through this thread. Do you know if part 84515287 or 84515395 have the camera and harness? The parts schematics I've looked at are not very clear.
  9. Did you use the Spoiler Assembly 8447008 and if so did it come with the harness ( not the Coax )?
  10. Getting ready to order parts for this Mod. Mirror 13532977 Coax 84335461 Spoiler assembly 84487008 For the SA there are other numbers in this thread that others have used, 84515287 and 84515395. Which is the updated/correct part number for the SA? Also mentioned is a Harness 84599550, will this be needed?
  11. My concern would be are the trailer tires rated for 80mph.
  12. Ordered my 21 Sierra 1500 6.2 SLT, Premium Plus Package, X31, Cayenne Red Tintcoat, Dark Walnut/Slate on 11/2/20. Schedule build week of 3/22. Doing my Happy Dance!
  13. For the GMC X31 package what badging do they have on the mats, X31, GMC?
  14. For GMC Sierras the front are 84420655 and the rear are 84420656.
  15. Ordered a Sierra SLT, Premium Plus package, X31 6.2 on 11/2, still event code 1100. My dealer has an allocation of 10 orders per month and due to constants only one can be ordered with the 6.2. The good news is my truck will be the next 6.2. Mine is a 1500, didn't realize this was a 2500 post.
  16. I had a 99 GMC Sierra classic which was the old body style, sold it 12 years ago. Another way to tell between the two is the old body style came with the 5.7 and the new came with 5.3s.
  17. Not an expert but The K in front of the number used to mean 4 wheel drive. Another thing to keep in mind is1999 was a transition year for the new GMT 800 platform as well as still producing the prior GMT 400. So there were Two body styles in 99. Hope that helps.
  18. I have been running Mobile 1 oil and filter on my 08 since almost new. My oil pressures are exactly same as yours.
  19. On my 2008 Sierra when I removed the OnStar module and drove the truck it threw codes, Service four wheel drive, ABS light and engine light. When I reinstalled it the codes reset and went away. Not sure if there's a work around with tech2, but I kind doubt it. Maybe you can try relocating it?
  20. Doug, Are the interior colors on your truck Dark Slate/Walnut? I prefer that to the Jet Black. It goes very well with your exterior color on your truck! Cheers Dennis
  21. The X31 package is $850 for the Sierra which includes Hill descent control, Skid Plates, High Capacity Air filter and X31 badging, wonder what the badging is? Also included 2 speed transfer, p265/65 15 All terrain tires and Dual exhaust!... Interesting
  22. I will be curious to see if the K47 High Capacity Air Filter will be interchangeable with the standard filter as in years prior, or if the air box is different now on the 19s. Looks like the only way to get the K47 option is with the X31 off-road or VYU Snow Plow Prep package.
  23. I went with AC Delco Durastop when I had the rear drums done, I think they were like $65 at Rock Auto.
  24. Our year trucks do not use a PCV valve, not sure what year they began omitting them. The revised valve cover has a baffle in it to prevent it from sucking oil.
