I don't want a cab leak. Back glass rubber corner detached

hey guys I did a pro grill swap on my 21 mgm I bought everything from the dealer but the garnish piece although clipped in wiggles like its loose is there some way to tighten it? Did I get a bad grille or garnish. I went up to it and tried to move the garnish on a 21 lunar rock and it feels definitely more secure. I just don't want this garnish popping off because it is pretty pricey.

And lastly the back bottom corner square shaped window rubber piece has torn free in a corner. I don't want a cab leak. Is this a warranty item? Hate to have to replace it with it being so new.

Thank you guys for your help.

 

It was the same for me with my grille swap. The garnish snapped in but wiggled considerably. I actually put a bit of adhesive in behind it and now it's solid.

Is it possible for you to post a picture of your window issue? If it's what I am thinking it is, then I would say yes your dealer ought to be able to fix it under warranty.

 

With a 2021 truck I'd be at the dealer getting both of those items addressed... under warranty.

 

Yeah I'll post a pic were you aware the pro grille actually requires two retention washers that a lot of how to's and videos fail to mention? I have the part number if you need it
