What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[89Suburban]

Operation Quiet Down has started.

Amazon delivered a B shape self adhesive weatherstrip.

After looking at the rear doors which have full 360 degree inner and outers, the fronts have an inner but the outer is broken into areas.

I added a third seal un the upper forward portion of the B pillar.

It is outlined in orange. I did a better job on the passenger side... but both doors still function- no road test yet.

The next job is when the u shaped weatherstrip arrives and will put it on the the lower leading edge of the rear door continuing the weartherstrip thats there...

You peaked my interest here. I replaced my original seal and the new one fuggin leaks air, like REALLY drafty around the bottom half of the door you can feel it on your left leg or if you reach down. And of course the means cold draft in the winter/hot draft in the summer. Really pisses me off I paid good money for that seal and it matches the old one.


Is that a decent quality seal you got there from Amazon? Is the adhesive strong? Got a link?

Its a Generic B profile- https://www.amazon.com/gp/product/B0771T61VH/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

The best is to figure out what thype of profile- you may need a P profile.

My Denali is 8 years old so the old weatherstripping is compressing.

Did you replace the one around the door opening or the one on the door?

The one around the opening. Looks identical to the old one. Don't know why I have such nasty draft. I adjusted the door striker in to get rid of it and it doesn't match the body lines on the outside so I backed it back out, pisses me off. And of course where there is a breeze there is road noise as well.

You’ve been fighting that for awhile haven’t you?

Yes sir, still looking for a fix.

Is there something I can put on the seal to shut the door and see where the gaps are? Some kind of marking material? Chalk??

I wonder if one of your hinges is a little bent. That'll cause that too.

 

[gooffeyguy]

Are all those pics of the new seal?

What's that stuff hanging out of the bottom center area?

maybe a sheet of aluminum foil, close the door on it and see where it bends and where it doesn't

 

[gooffeyguy]

Also looks like you may have the striker a bit too high, looking at the lines where the front door meets the rear door

Some kind of inner cord? Yeah that’s how it came. ****** up aint it?

I know when adjusting doors and stuff on other vehicles a trick used is taking a dollar bill and close the door on it with half inside and half outside. You should be able to pull the dollar bill out without too much effort.

.....or something like that

When I close it it is nice and smooth latching action. I don’t notice any dragging or lifting as the latch engages the striker. You would think with the miles this thing has it would actually be hanging lower.

Snap a pic of the bottom edge of the door with it open. Hows that rubber flap/seal that wuns along the inside bottom and covers the drain plugs?

I like that that seems like a cool trick of the trade.
