Well that seems to be a much simpler solution than the original TSB. Would of saved alot of owners some headaches and trouble if thats the case? Did GM redesign the bolts or do they instruct the dealers to apply sealant every time before the bolts are reinstalled?

So it seems now that the real source of the leak are these spoiler bolts that are not properly sealed with the sealant? So water passes through them and soakes the headliners?

Ive always wondered this myself. Ever since my window was replaced , it has been problem free. My dealer works with an auto glass company that is contracted out. Im wondering if some dealers just have the techs do the replacement.

2019 Sierra SLT. Built in Mexico 07/2019. Discovered window leak beginning of 02/20. Entire window assembly has been replaced with the new updated window part number. Keeping a constant eye for any new leaks

The TSB is useless if the glass frame is cracked. I would push for a new window installed by a glass company

Well ...haha the spoiler is attached and its on there tight so I'm hoping theres new hardware on there now.

Also, does anyone know where these go? They were left on the roof of my truck after the install. Hoping its old hardware from the damaged window and that they were replaced lol

Here is my window that was just recently installed as of last Thursday Feb 13th

Greeeeeat. Keep us posted please

Just picked up my truck, and from what i can see, looks like the dealer/window installer did a good job. Headliner and trim pieces look good. The part number of my new window is the FAYUO 43R-000072. The same that other members have received. So time will tell if this window leaks as well and as always will keep everyone posted

Well thats a new one. With the way those lines are running above the slider, maybe an issue with the defroster? Either way please let us know what the dealer says. With the water leak issues and now this, not very encouraging with these rear glass issues

Thank you for the clarification. Im interested to know what the possible changes/differences are as well

Could these numbers on the window be lot numbers rather than model numbers? My window that is currently leaking has different numbers than the ones posted in this thread.

My entire glass assembly should be arriving today and the dealer has a glass company they contract out to do the install. They also advised me that the truck will sit indoors after the install for 24 hours before I can pick it up. Im hoping this resolves the issue but like anything else ill be paranoid and keeping a constant eye on it all the time now

So it seems that the only real hope is a brand new rear glass assembly. But even then..
