Hello, new to this forum and unfortunately also new member to the rear window leak club on my 2020 Silverado trail boss for which I am the original owner. Leak started (or first noticed) December 19 after trip trough the same car wash I've been using for 3 years. No signs of wet headliner. Truck is kept in garage, though it was parked outside after it had rained and temp dropped to the lower 20's. I suspect the plastic frame cracked after being wet and freezing. I've read through majority of this thread over the past week, as well as the other thread DIY sliding window leak permanent repair started by Leevon. Tons of great info on these threads. Obviously truck is out of warranty and I plan to fix this myself over the holiday weekend. Few questions before I get started. 1) What is the torque specs for reinstalling the nuts and bolts on the spoiler? I assume it isn't a lot. TSB 18-NA-383 doesn't mention it and referrers to a process in "SI", whatever that is. I recall reading somewhere in here that some spoilers were damaged by dealerships due to over tightening. 2) For those who sealed the window themselves early on, how well has the repair held up? 3) Any reoccurring leaks? Thanks.
