Just did this myself. I tried sealing around the spoiler first and it definitely slowed it down, but there was still a slight leak. Not a soaked headliner like it was before the fix but enough I didn't want to leave it. Watched the video on the first paged for the headliner removal. There was two extended mounts for the headliner which I didn't see in the video so thought I was missing something but you just gotta pull a little harder and it'll pull off the glue and you can drop the back half of the headliner. Those were located next to the rear window. Definitely can do it without pulling the whole thing out. I also used the 3M strip caulk around every hole for the spoiler. Just did it yesterday so letting it sit for the weekend then I'll wash my truck and see what happens. All in all, took me maybe 3-4 hours but let the sealant sit for an hour before pulling the tape out and putting the spoiler back on and putting my truck back together. Didn't take as long as I was expecting.

I may have to remove the rear spoiler. It's still leaking in but not nearly as bad. So guess I'll cut all the silicone out and pull the headliner out then the spoiler and seal it all. Either that or I clean it up and trade the truck off.

2019 chevy 1500 high country and my 2022 chevy tahoe high country. 2019 chevy 1500 5.3L has been blacked out, 22" fuel wheels, diode dynamics fog lights and avs lighted bug deflector. 2022 Tahoe 6.2L has been blacked out, tinted tail light

Ya I saw that so I bought some but looks like I may be returning it unless I use it in the gap between the lower spoiler and rear window. I laid a nice bead between the cab and upper spoiler then wrapped it around the sides of the spoiler as a just in case. Can't see it unless you're looking for it. Ended up buying the permanent 81730 to fill it. The test will be Monday so guess I'll find out how well I did lol. We're in a level 4 for severe weather so there's a chance I may end up with a new truck anyway lol. Definitely love this truck and just got it where I want it so it would be a shame to have to get rid of it.

New member and have the same problem with my 2019 high country with the rear slider, truck has 71k miles and its the first time my head liner has been wet. I noticed water marks on my rear window a couple times and on my rear seat but never thought anything of it since I fish in the rain lot and figured it was from opening my door in the rain to grab things out of my truck. Yesterday we got about a half inch of rain and I noticed my headliner was soaked. Read through most of the 235 pages and figured I'd give it a shot so bought most of what everyone was doing so I can fix it to.orrow since I'm drying everything out. One thing I noticed was my gap between my cab and spoiler isn't even, if fact there's a spot where it's so tight it chipped the paint off. Anyone else have this? Looking at the pictures it seems there's a pretty decent gap there for most people.
