Trunk Jack Area Under Water

[5Toes]

The other day I noticed lots of water in my trunk's jack area! Well today in attempt to fix my sunroof (the elephant drain was so dirty!!!) I sucked out all the water and pulled that corner's carpet back.

I couldn't fidn the source! I looked hard but could think of nothing. I searched on the interwebz but could really find anything...

so any ideas??

Tail light gasket.

Tail light gasket.

Ya thats a possibility too but late model tail lights have much better gaskets so its not as common of a problem. Good catch though. (wheres my lift stick? lol)

^ All probably wrong. None of those things will let in that much water in, only a small amount.
I had the same problem and it was none of those things.

It's the drain for the rear windshield. You can see how it drains by removing the rear shelf(that the rear speakers sit in). That is probably clogged and overflowing.

^ thanks.

Lol my car I bought with a 95% dry trunk :)

I saw that rubber tube that is pretty long that hooks into that plastic bracket thing. it was fine.

Tail light seals were supposedly done a year and half ago. I pulled the tail light cover that side, totally dry. So yeah

Remember I am talking like 3 inches of water here. The antenna grommet is kind of lose, but it cant be THAT lose.

Trunk seal is nice and flexible, it isnt that

Again wrong. I had standing water in my trunk. First I inspected the drains, nothing, clean as can be with no leaks. Then the C pillar trim and antenna grommet, still nothing. Finally after much dismissal, I tried the taillight gaskets. They didn't look very worn but to my surprise it completely fixed the issue.

Well I have a receipt for them being replaced a year and a half ago. Though it may only be one side, I will check the receipt.

Either way, I couldn't even find where the rear sunroof drains were!

I had a spot weld broken on the trunk hinge and it let in ridiculous amounts of water.

I do have an early model for the record, although I don't see a late being much different. Pour a glass of water through the rearward drains, pull the side trim inside your trunk and you should see down near the jack area the little plastic tray fill with water. On the other side is the part covered by the bumper where the water overflows and drains. It looks like a sort of side vent.

I Will look around closer than

Under my tail light is a sort of serious patch of rust. So that may be the culprit, but when I pulled the carpet it didn't look like there was a way into the trunk from there. and if there was a way in from that point, the water would drain out of that spot too dont you think?

Will do, but I am confused about this "plastic part" What does the drain going into this area look like?

^ He's talking about the plastic tray that the rubber hoses lead to from the front of the car. You have to take out the trim to see this. Inside that plastic piece is a hole that leads to the outside which allows the water to leave the car.
So when you test for proper draining, such as putting water in the sunroof, you should see water going in there and draining out on the other side, near the bumper on the side of the car.
