The other day I decided to pump up all my tires including my spare and when I was in the trunk I noticed in that the spare tire was sitting in some water. I dried it up and started looking for a leak. Not finding any rust or obvious source of water I started Googling which lead me here. I searched and read some of the other threads. I have 2 questions.
#1 I need to buy replacement plastic clips to keep the lining on the trunk lid its self. I broke a few when I removed it to seal some of the seams with silicone. Does anyone have a part number for this?
#2 My main trunk seal looks good. I really dont think its the problem. However the seal around the rear window where it intersects with the trunk looks more warn than the others and it looks a little loose. This looks like it would be a very expensive part to replace because it looks like it goes all the way around the window and would require the window to be removed. Does anyone have any ideas of what I could put underneath this seal to prop it up alittle more so it makes a better seal?
Does anyone else have any other ideas where the water is coming in at?

The only way that you are going to find that leak is to take everything out of the trunk & then get in the trunk with a flashlight & look for the leak while someone sprays water on the rear of the car from the top, the sides & the bottom.

lol the trunks are plenty big to fit in and if not, grab some tiny person throw them in your trunk and tell them ull let them out when they find the leaking water lol

LOL I did that. The neighbors came over and started to ask questions. When I did that I couldn't find any leaks at all. |

Again this question? The most common is down the rear wall of the trunk. RIGHT UNDER YOUR NOSE!
the trunk seal is the problem the cure is to fill it full of silicone and replace it. You didnt believe me in the other threads?

You didnt believe me in the other threads? What do you mean replace AND fill full of silicone? Do you have the part# for the seal? Can you recommend a good place to get it? What do I attach it with? |

you dont need to buy a new one, just take loose the old one and pump silicon in it. then put it back on. Look at the trunk leak thread here somewhere in the 2nd gen section

aurora2001tan's recomendation is exactly what I would do. It only costs about $4.00 for a tube of silicone caulk and it fixed my trunk in about 5 minutes. Just grab hold of the rubber "gasket" that runs the perimeter of the trunk opening and pull it off. Clean in it up and then squirt a generous amount of silicone into the groove that fits over the metal lip of the trunk. Then, put the seal back on. I bet you have a 99% chance of fixing the problem by doing that for 5 minutes work and $4.00.

I want to put silicone under where the red arrow is right? I will clean up the outside of the seal, take the seal off, clean up under it, put a bead of silicone down on where the red arrow is then do I let it dry or put the seal on right away? Thanks for your guys help |

I did this, I took the seal off and filled the v that goes around the lip with silicon caulk. I thought a bit about putting the caulk on the metal lip itself, but decided to do it the way everyone described here. Worked like a charm!
Put the seal back on while the caulk is wet - otherwise it will not go back on at all.
If you pull a few inches (about a foot) off, I think it will be obvious where to put the caulk. You can always put it back on right away.

yeah the v that goes over the steel ridge. Mine has some factory silicone in it. it fails that why it leaks. the picture looks strange and I cant tell where the seal goes on the metal ridge. In the center of the trunk rear.......the ridge stops and there is a gap......you can see with the seal pulled off. . Thats where the water comes in at. Runs down seal, gets into seal....then to the gap in the metal.

I too had the leak on my 2001. Some had suggested here that it was the 2 piece trunk lids with the license plate insert that had the leaks. Mine doesn't have this but leaked anyway. I checked it right after it rained and observed that water defied gravity and ran up under the gasket onto a seam and rolled to the middle to run into the trunk right below the U shaped bolt that latches the lid closed. I pulled several feet of the gasket off and applied silicone and put the gasket back down. I just checked the trunk after one of our FLorida downpours and it is dry. The slilicone is the way to go, and easy too! Buy the way, can anyone tell us why some trunk lids have the two piece design? My first thougth was that they made it like that for the European market that uses larger tags. But GM had already killed Olds, so there weren't going to be exports. Anyone got a guess?

Im sure it came down to the trunk material and the tool or the mold that stamped it out. The one piece is Aluminum and all the 3.5's are steel... so they had to engineer two molds and two seperate processs anyway. The one piece for sure cut costs or evened the cost for an aluminum part. Thats my guess.

I wanted to let everyone know that I did the silicone around the main seal like everyone suggested. It does fit much better now. It has not rained since doing the mod but I hope this will work, if not i will do the truck mod like suggested.

You didnt believe me in the other threads? The leaky trunk found me as well. I found the spare tire well dripping the other day - it hadn't rained for a couple of weeks, but I was getting a drip from the seam where the spare tire well mates up with the rear panel. Sucked out the water. Dried it and waited for rain. Friday night that came. Short drive in the rain put more water in the trunk. Dried it again on Saturday and left the car sit outside in the light rain. By early afternoon, we've got water about 1/2 inch deep in the spare tire well. It's exactly like Tan says - the water runs down the seal and then wicks its way past the seal labyrinth into the trunk. The water runs down right at the latch- that's the low point. The seal was wet inside the vee that pushes over the steel lip all along the bottom of the trunk lid. All dry everywhere else. All siliconed up now (BTW the factory stuff looks like hot melt adhesive, not silicone) all we need is rain to prove it's fixed. |

Can you tell me what kind/brand of silicon you used, and exactly how much and where you applied it? I have the same problem. Thanks! |

I used the $4 a tube clear stuff from my local hardware store - 100% silicone. I cut the tip small, pushed the tip down in the split in the seal that fits over the lip and filled it up - took way less than half a tube.
I took the gasket completely off the car and did it on the floor of the garage, but you would probably be all right if you just did the section from the hinges back. The problem is that the water runs down the waterfall and back inside the trunk right at the latch on level ground.

Just an update, I did the sillicone sealer this summer and since then every thing has been nice and dry. I put the sillicone under the main black trunk seal and everything is fine.

I had a leak problem in my 2002 wheelwell. It had 4" of water in it
The water was coming in from the drain tube from the roof drip rail. There are tubes in the trunk behind the trunk liner on both sides, that come down from the roof and connect to a plastic fitting that drains the water to the road. One of these had come off and all the water was ending up in the wheelwell. I re-connected it and have had no water since.
