I have a 2004 Pontiac Sunfire, and I've had it for about 4-5 months. And I noticed the truck was leaking, while doing some work to my system. Has anyone else had this problem? What do I do to fix it?

I had a 6" pool of water in my spare tire well and a soaked backseat, I pulled off the taillight reinforced the seal on the light with insulating foam and adjusted the seal for my trunklid, problem solved.

Pull the trunk carpet and look into the trunk from inside the car and anywhere you see light...seal it up?

My 2004 Sunfire was leaking into the trunk through that flapper thing behind the carpet in the trunk on the passenger side inner quarter panel. I removed the flapper and sealed up the hole with a piece of plastic and silicon.

So I checked it out, and siliconed where I think it was leaking from. I'm gonna pour some water around the trunk and see if its still leaking. Hopefully I fixed it though.

ya i had that problem too, so when i got my new tails i siliconed those holes up like there was no tommorrow and it dont leak so much anymore

thats a weird spot if its what im thinking it is thats the pressure release port for cabin pressure. earlier js had it in the pass door jamb.

I had the same problem with the flapper thing being stuck open.Put a plastic piece in and siliconed it up never had water again..noticed a few times going through pressure car washers a bit of water..but have yet to worrie about it.

Not to bring up an old post... but I would rather do that than make a new one

My trunk had been leaking for quite some time and I never could figure out where it was coming from...
I am hoping this is where it is, as I have now hammered down the plug, and gooped it up. Lets see if I still have wet carpet after this

Looking up from under the car


Inside the trunk, you can see it is lifted away

Again


Just posted to let people know if they're having a leaking trunk, this might be a good place to start looking

god i need to get around to doing this. i have just been to busy and it has been raining to much

i have a 96 and it did the same thing i think it was the antenna oddly enough. when i drive and the roads are wet you can really hear the road/water noise in the rear almost like the window is down or something but it doesnt seem to be leaking. does anyone ese notice that noise?
