D-pillar replacement vent (not the cover)

[89Suburban]

I need these too. I popped off my accents to clean underneath of them and I have one of the flaps missing on my drivers side. Glad this got bumped, thanks.

Yet another item I have not considered on my Denali. I will have to pop my covers off and check them. Solid info!

Can't find the correct name for these anywhere. I'm not looking for the exterior cover, I'm looking for the piece that goes under them.

Black plastic thing with little rubber flaps to release cabin pressure or something. Mine are missing several of the flaps and I occasionally have to travel on gravel. The entire truck fills up with dust because these stupid things obviously don't seal correctly with missing parts/rubber flaps. Anyone know a part number or the correct name for them?

Thanks!!

2000-2014 GM part # 15816854 - Body Pressure Relief Valve

I need to replace the drivers side also and ordered two used OEM ones from eBay for $ 14.00 but they are called "Pressure Relief Valves"


New Part # GM 15816854

Old Part # GM 15756444

Good morning, all, so I received my two "body Pressure relief" valves from a seller on eBay yesterday (GM 15756444) and went to replace the old ones and noticed that the ones that were presently installed in my 2011 be very different (see picture old on the left and new on the right) The old ones have NO rubber valve flaps installed while the new ones did. Just kind of weird and this would explain my dust intrusion into the rear of the truck.
