yeah i would ditch the spare too but i dont like how the rear looks without it... maybe ill just have a spare airbrushed on the back?

Dealerships have a tendancy to rape people for work they want done. When I was looking at an H2, they wanted $2500 for chrome goodies, that would cost me about $900-$1000.

I have a good contact up in the NW. A small little body shop off of McKnight in the industrial area there. The shop is called K&J Autobody and the guy to talk to there is keith. I actually picked up his name from a different car forum. He does alot of work with import sport compact cars and their fiberglass body kits. Of course he does everything else too, but it is definately a good price. I got quoted from SHAW nearly $300 more for the same job. </div></BLOCKQUOTE>

All vehicles have this, usually hidden under the rear bumper.

I allows you to close the doors and release the inside air pressure. without it the door will not close because it is to air tight in the cabin. </div></BLOCKQUOTE>

hehe -- so w/out you wouldn't be able to close the doors? Or would it just make your head explode if you were inside the cabin...

Cool vent, blow the dealers mind and tell him you have a hole in your hummer.
Removing the spare makes me wonder if GOBI is going to put a ladder there for the roof rack??


You'll see in the next week or two.

you need to have a vent...or your windows will pop after a while. At least the seals will...if not the glass.

do a little bit math and an increase of 30 degrees in cabin would result in an increase of about 30% in pressure inside the cabin... I wonder how much pressure would make it go *POP*

I bet your right. The new cabins on cars/trucks are very air tight.

Yes it's the pressure relief for the truck to relieve pressure when you shut the doors. The original was smaller and wouldn't allow the doors to shut good. Be careful, I think I would try to get it installed somewhere else or you might not be able to shut the doors, and or damage something else. We started building S10's one year and the valve was too small and the rear windows would basically blow out from the pressure. Needless to say they changed them to a bigger one.

I checked with engineering and they said.

A BIG NO NO...ALSO THE WINDOWS WILL FOG BEYOND THE DEFROSTER TO. The air and heater will not function correctly..you need negative pressure to curculate air.

Just checked

Well even with all the naysayers, the duct tape experiment had to commence!

I realize that it isn't entirely representative what the difference will be when it is welded shut but it should give a reasonable idea......on with the pics.




So as for the results of my tests, which are by no means conclusive.......

Door opening ease - UNCHANGED
Door closing ease - UNCHANGED
Wind Noise - UNCHANGED
Sunroof Wind Noise - UNCHANGED

Sense of cabin pressure when closing or opening doors - UNCHANGED

I can basically see no noticeable difference in any area at this time.

I do see it definately being related to the air\AC\Heater because, and correct me if I am wrong here, in order for the air to flow to the back of the vehicle there needs to be some suction pulling it. Removing the vent essentially leaves no way for the air to circulate to the back of the vehicle. And since there is no rear vents that i can see.....this would mean that the rear passengers and cargo area wouldn't get air circulated to them nearly as efficiently.

This definately falls into line with H3Lady's post and makes sense engineering wise as well. Also makes logic sense for the rear defroster condensing too.

So I am still going ahead with this project. If I find it noticeably uncomfortable for the air circulation then I will consider a vent relocation, perhaps in the fender well.

So if something happens to the ac/heating system,windows popping,etc....warranty is void...?

Everyone tends to forget. Dealerships, as with any business, are open to MAKE MONEY. They are not there to just break even. Just any mechanic if he works for free. Part of the price is the install. I'm not saying that $2500 isn't out of line, but you guys need to look at the bigger picture.

90 Percent correct. It does help to relieve pressure inside the vehicle when the door is closed or temps rise.
The volume of air that is dispersed inside the cabin when a door is closed is considerably greater than the size of the valve. Its primary purpose is for airflow for the HVAC system. That might be the reason that the person responsible for this vent in the product engineering area of GM is also the HVAC product person.

It's going to cost $800 for the full shave....was going to be $650 if I just filled the holes and patched the vent. We decided to go with the full shave though after photoshopping all options....actually, I'll post all options here for you to see so you can decide which you like better!

It goes into the shop on this MONDAY and they'll have it for two days, and then I will be posting new, freshly painted pics!!!!

In regards to f5fstop: I totally agree that it does have a purpose in relieving pressure due to temperature changes and in opening\closing the doors. However, I would be very very hard pressed to believe that the vehicle is so air tight that without that vent, it might blow out the windows if it gets hot enough.

Nice job...I like pic 3 and 6, particularly 6 though.

I would have to second that.

Number 6 is my vote

Are you guys saying that you like the H3 in the center???

I think that one looks totally off...looks empty in the bottom left now.

#3 is a cleaner look, but #6 looks like the logo is supposed to be there.

How about pic #3, but with the logo in the center?
