Thanks I saw that, but dealer say operating as designed. If I was able get service operation description I could challenge them..I really hate dealer BS
Is the service manual available for 2021 Denali Yukon? I looked on Helm website and not there. Is there another supplier. I need to see heater operation and front floor duct locations. No air comes out full force
I am going to tape it up, if I get a chance this weekend. Hopefully, I can isolate it. It sounds like previous generation where pillar covers were causing wind noise
I have wind noise on pass side when driving over 30. I had the problem with previous generation. I checked pillar covers and they are loose. I am going to tape them to prevent air from getting under them to see it it eliminates the noise.
Installed GM mat in cargo area. It is not cut exactly to fit, plus the way it was packed, is was folded and now has fold memory..is it just me or is it a crappy fit? The previous generation mat was perfect and stayed in place. This one is shit
Have new question-
How does GM determine which type of truck (suburban, Yukon ) is produced a certain week? Is it based on colors, options, delivery location? I assume sold orders are given priority, but then how does the production filter out?
Thanks
