Default Quarter Panel Pressure Vent location?

Anyone know where the quarter panel pressure vent is located? I pulled into the garage this afternoon to find a part laying on the ground. It is PN 22702778. It is a black plastic piece with two vents. It was on the passenger side, but I have not idea where it goes.

Any help is appreciated, dont really want any open holes on the car

Thanks.

Noticed this thread sitting out there with no responses. Did you find the location yet? I am not completely sure, but my guess would be in the wheel well under the fender liner. Let'* bump this up to get you an answer.

Anybody have any ideas? I checked the wheel wells and did not find anything. Looked on the internet, lots of them out there, but no pics of the location.

UGH.

Ugh is right. I meant to do some research on this but got distracted. Never heard of the problem. I'll dig around after dinner. Is this the gas tank pressure vent?

Its a PRV, or pressure release valve. It provides an outlet for air when you shut the doors, or you would pop your eardrums. I noticed a picture last week of another member'* trunk with all the trim removed, and I thought I saw it on the right hand quarter panel. Pull the liner from the right side of your trunk and you may see it there. I will look at my car when I get a chance.

It has to be somewhere where air can flow to it from the passenger compartment.

Ding, ding, ding.............we have a winner.

Passenger side quarterpanel in the trunk, under the carpet.

How does something like that breakoff one might ask???? Well, you put a couple of pumpkins in the trunk for your kids. You corner slightly hard(GXP you know) and you hear a loud thud of the pumpkin hitting the inside of the trunk. Evidently, busting the plastic retainers, resulting in the part falling out.

Wow, never would have gone there.

Thanks a bunch for the help.

Glad to help. Partial payback for selling me that LS1M scanner. Bought new batteries for the Palms and it works great.

Glad to hear its figured out. Great call, Roy. I was thinking, what if it'* a common problem and a lot of us are missing them and aren't lucky enough to find it in the garage. I either dont have one in my Dodge truck or it'* filled wth a mouse/mole nest. It has always been hard to close a door to fully and ya, you can get the eardrum effect when you slam it.

In a vehicle with a single exhaust outlet, the PRV will always be on the opposite side of the vehicle as the exhaust outlet to avoid exhaust being pulled into the passenger compartment. On a car with dual exhaust, the PRV will usually be on the passenger side to maximize distance to the driver.
