i did do a search i did not find what i was looking for so heres my question. most times when i close my doors with the windows up i feel a gush of wind coming out of the car and i have to slam the door to get it close what is rong and how do i fix this problem

Have you checked the pressure relief valve mounted in the door frame on each side of the car?

your problem comes from the fact that you're trying to shut the door with the window up. when you shut the door, it pushes more air into the cabin, so the resistance you're feeling is the door compressing the air inside. how to fix this? like trickster said, check the pressure relief valves on the door frames. make sure they're not clogged up...that could be causing your problem. autozone (or any of those kind of places) sells air-hose fittings that connect to the p.r.v.'s. if your p.r.v. doesn't look clogged, hook up an air-hose and check the pressure. a good p.r.v. should read about 5 psi. hope this helps..

edit: if you're in need of a new p.r.v., check the junkyard, or you can order it from www.tupperware.com

Say what? Since when did TGO become "Insert R!cer Forum Name Here"?

Your door hinges are probably shot. In rare cases, you may have actual frame damage that has the car slightly twisted. It is most likely the hinges though.

Do you have the "tilt-in/tilt-out" angle of the window glass adjusted properly? If the side glass is tilted to far in towards the cabin, you can have alot of problems closing the doors.

When you roll up the windows, try leaving a slight 1/4 or 1/8 inch gap at the top. That way you're not forcing the all the cabin air pressure against the door when you close it. No need to put extra strain on the door glass unless you like to adjust it periodically.

humm where is this pressure realease valve at? and what does it look like?

Here it is!!!

how do i check if the tilt-in/tilt-out" angle of the window glass to see if it is right also what would the right ange be?

i knew hte trickster would have a pic of that heh...

I didnt knwo that that is what that part was called....in all honesty i thought it was there to help cousin the door form scraping the body....heh and now i know....thanks man

as to how to check the angle....

here is how I would do it...

slowly close your door with the window all the way up....and look and make sure the glass is aligned with the weatherstripping of the t-top o roof of the car....if it is than you are good to go...

you jsut have to kinda eye ball it to tell really...

i pulled those vent thingys off, they rattle when the bass hits so i have no pressure relief valves i guess. oh well, its easy to close my doors.

Same here, anyone know how to fix the rattling? I just used dynomat on the back but now no air can get through. Any ideas? Thanks

The rattling is covered on the Car Audio forum. If you remove them, they still perform their function, you just risk getting crap in the body of the car. I too had no idea they were "pressure release valves." I saw a diagram of the cabin air flow and I assumed they're just part of the ventilation.

lol, so they really are pressure release valves? i posted way up at the top of this thread, and i went off on why these were needed to shut the doors because of cabin pressure, but i was just bs'ing to be funny. that's kinda weird that i was trying to bs, but was correct for the most part

edit: either that, or i'm about to feel like a dumbass when somebody tells us they've been pulling our leg all along

That'll teach you not to play with Tupperware!!

Oh lord you damn kids and your tupperware!!! Good thing GM knew these cars were for retards from the get go.. thats why they installed the wonderful giant plastic screws for the interior kinda reminensent of playschools my first interior.

Anyways to change the placement of the window take your door panel off by removing the arm rest and then handle etc... pull the panel off and lift from the bottom and it should slide right out make sure the window is down tho (if you need more info pm me.. its pretty easy tho) once you get it off youll see two white things just under the top of the door that hold the window in place when its fully erect (cough) you can loosen them and move them in and out and the window will change placement when its all the way up ... this is really good easy fix if you have leaky windows!!

But it looks like your problem is more operator error...... consult you local gym to help your ailment.

Oh and to get the "pressure release valves" from vibrating cut out all the little paper pieces in the back and then put a bead of silicone around the opening when remounting (or just jam somthing in there, felt works good too) and a little where the bolt to hold them is too...... or you could just take them out its alot easier.

operator error...... i know i should have consulted my gym a long time ago!

Pressure relief valves? I'm not too sure of that. I think their primary function is for cabin air ventilation.

When "vent" windows were eliminated from most GM vehicles back in '68, those vent thingies were put into the pillar post.

GM calls them pressure relief valves, and I don't know how they could contribute much to ventilation when the door is closed.

I'm not certain they 'relieve' anything myself just from the way they are designed. They certainly don't function when a door is shut to relieve cabin pressure. By this I mean, there are rubber 'flappers' on the backside that only 'relieve' air when it is blowing from the outside in. When shutting a door, cabin pressure is pushing from inside out. The 'flappers' are the same design used in oiless air compressors, they work one way and one way only.
From my exp. of owning hachback cars, they generally require a little extra 'oomph' to shut the door all the way over a car with a seperate trunk. Also, the better the seals are all around the car, the harder it is to shut the door.
My opinion only though....

Maybe it for when the windows are open?

So when you are driving around, any air that ends up inside of the door leave through the PRV?

I have no clue.

Sorry guys, they are pressure release valves. You wanna find out how well they work? Try blocking the hole off with a sealed plate...
You'll find the same valve on trucks,, at the bottom of the door, (now the Silverado puts them on the back of the cab)

I remember way back when I had my 92 bird and big 6x9's They kept making a lot of noise. I took the flaps off and glued a flat piece of plastic to it. The car was then very sealed and took a lot of effort to close. Something my girlfriend never could master and probably attributed to the power lock actuator going out prematurely.. From having to unlock the doors again and have her re-shut the door.

One of the rare cases why a C6 is better

Their windows roll down a fraction of an inch when you open them, and will stay down until the door is closed then go back up to make the seal........

No reason why you couldn't make your thirdgen do that...I am sure it is just a sensor and probably a small chip...i wonder if you can order the parts from GM. Hmm, time to check alldata for the wiring schematics for the C6.
