Rear window leak - add flashing or reinforcement?

[mandrewbot3k]

My '22 LT just started leaking in June, 1 month out of warranty.... Definitely cracked window frame as documented.

 

I plan to do the TSB seal myself, but to avoid future issues, I'm wondering if anyone has anyone tried adding some kind of plastic drip edge to direct the water over the glass edge rather than pool up behind? It won't prevent the cracking, but would ideally reduce the amount of water pooling up. Alternatively, thinking just adding a few more layers of seam sealer so the level is above the edge of the glass.

 

Also curious if anyone has considered setting an aluminum rod or bar into the seam sealer in hopes that it would make the plastic frame more rigid and prevent future cracks from forming. 

 

Luckily the leak is pretty minor right now, but it's annoying none-the-less considering the electronics on the back of the cab and the potential for mold in the headliner and carpet.

Only way to fix is drop the rear headliner, unbolt the rear spolier and add in some flowable silcone in the crack between the glass and cab. All of my Rams had this issue, the GMs need the rear spoiler off to clean and apply the sealer, once you do it it should be good for 5-10 years. Apply it heavy. It sounds like a pain and it is, took me 3 hours to do, but really not to bad.

This is what worked for me.

Easier said than done… it requires a 10mm socket and god knows where those ran off to…lol. 

 

But, Yeah… I’ve read all the posts going back years and was thankful when I had my 2019 1500 with the fixed rear window. Made the naive assumption that GM fixed the issue three model years later.

 

i plan on doing the seal from the TSB, but have also seen many say that it will continue to form cracks and continue to leak. Maybe the SEM product will work better than the early TSB fixes in the 2019-2020 1500s.
