Barn Door Weatherstrip

[99tahoemomma]

Had wet cargo carpet and found the weatherstrip on the sides of the barn doors was leaking. I ordered new weatherstripping for all the rear: upper strip, opening, and the vertical and corner pieces on the door. After installing all the new pieces, the passenger door wont close all the way at the top. Now its actually leaking worse than before. Anyone have any suggestions where you have ordered the parts and replaced these with no issues? It would be nice to drive in the rain

Not a direct answer for you, but there are a lot of posts here about barn door weatherstrip. One is here where there is an embedded video showing how to rejuvenate existing seals. This prompted me to go that route for my crew cab.

Door Seal Procurement and Acquisition (Best source and supplier)?

I would still like photos, but if you want a cheap route, get some silicone grease from 3m in a jar and get some fishing line(I think thats what he used)

Cargo door weatherstripping issues

my 99 tahoe has been having leaking at the barn/cargo doors where water will leak from the top of the doors and pool down at the bottom inside the vehicle. i bought the full LMC truck kit for around 260 which didnt solve the issue. on the LMC kit, the rubber that runs around the body is much...

Where's the leak coming from? Corners or middle?

Before I replaced everything, it was leaking from the sides near the window defrost sensors. Now it is leaking from the top where the passenger door doesn't completely shut. Used the weatherstrip discussed in the thread above... just ran a piece along the top of the passenger door that seals against the top piece of weatherstrip. Seems to be working so far....

There was a TSB for a revised weatherstrip which included a backer rod (of sorts) inside certain areas of the strip. Usually, its location is denoted by a paint mark and you’re supposed to line it up at a certain location. That might be something to look into.

I don’t have a better copy of it, but here is that TSB.

This shows that I've been installing the molding upside down. The start of the molding should be on the top and not the bottom. Mind Blown! This might fix my leak. LMC Truck sells their trim with a reinforcement in the middle of the weather stripping that goes around the door frames which causes the doors on the top to not seal tightly.
