William, are you sure it was the weatherstrip? Did you lay in the vehicle while someone sprayed down the vehicle?

What was letting water in the trunk was the weatherstrip for sure, I know because when I ran a bead of silicone around the lip before, it stopped leaking, until the silicone quit holding the water out.
Of course in the main reason it was letting the water in was from having the weatherstrip on the wrong way, the guys that installed my spear box that I used to have in there, they put it back on the wrong way.

I did not lay back there and have somebody spray water over it because where I live it is hard to get somebody to come out here, and my grandmother passed away last month, so I am alone now, except for my doggies.

The water getting into the floorboards could be coming from somewhere else, but I am hoping it was from the trunk.
If not it is probably a windows weatherstrip, or the wiper cowl/firewall somewhere.
My window weatherstrips seem like they are getting a little grime under them, so I was thinking of removing them, cleaning them, letting them dry, putting a little bead of SikaFlex in them, then put them back on.
I know I really need to remove my window inside trim, seats, and carpet, then have somebody hose it down while I sit in there and watch, but I don't have anybody to help, and I have a lot going on right now.

I should probably add a link to the new weatherstrip I bought, most places I found wanted a good bit more for it, I think I saved like 25.00 or so, it was still 100.00

Still have not had any rain, and with temps finally getting colder I am not sure we will, I may just have to take the car to a drive through car wash, then inspect the trunk afterwards.

If this stops the water from getting in the cars trunk, as well as the floor boards, then I am considering replacing my carpet since it has gathered quite a bit of mold.
I have a few questions, I thought about making a new thread, but if replacement of the carpet is needed because the trunk'* weatherstrip was incorrectly installed, than I'd rather have the info in this thread, so if another has a similar issue they will know what to do.

The sound deadening material, which I think is also a bit fireproof, it was soaked badly, and a lot of it has came apart, and has been thrown away.
If the carpet is still in good shape could I remove it, have it cleaned, maybe carefully scrubbed, and pressure washed, could it be possible to reuse it once I am done cleaning it, and letting it dry?
If so I could just get something to put down for the sound deadening material, not sure what to get though...
If I can reuse the carpet I'd save money, and be able to spend it on something else the car needs.
I did find some custom molded carpet that you can get a "mass backing" added to, but it is almost 260.00 for the "ultra plush" material with this backing.
And that is a little bit more than I was hoping to put into it, unless it is totally necessary to replace it to be sure all mold is gone.
I mainly hope to save money if possible because I still need to have something done with the headliner, if no more water gets in I could try to remove it, and have some new material glued onto the headliner board, I am not sure if I'll have to fill the holes from the Dorman headliner pins I put in to keep it from falling down on me, as it was pulling loose from all the moisture inside of the car from the leak.

Here is a place I found selling the carpet.
http://www.stockinteriors.com/AutoCa...d=3&ModelId=29

I see they sell it for with, or without Heat Vents, I have heat vents in the rear that come out of the middle console, so I am guessing that means without heat vents..

I would check all other leak potentials before assuming the water was coming from the trunk and investing in new carpet. Do you have a sunroof? If so, pour water in each of the four drain holes in the sunroof tub and observe if the water empties to the road at the wheel wells. I would also inspect all the door weather seals, and pull the door panels off to make sure the water shield is in place and doing its job. The butyl tape holding the plastic sheet in place can dry out and result in leaks.

I would not worry about replacing the sound deadener. At this point with a 1996 vehicle you are not worried about re-sale value and are mainly concerned with keeping the car on the road.

Unless you have a sunroof leak up at the headliner, the headliner face material dropped because the layer of foam starting to degrade and fell apart. If you decide to recover it, you have to thoroughly clean the old glue and foam off the hard substrate.

I agree.....if that carpet got wet, there will be a mold/mildew smell from it.....remove it completely, and hang it in the sun(depending where you live).....

Now while everything is out of the vehicle, you wet down the WHOLE car and look for leaks....as previously mentioned, from roof drains, water barriers in the doors, tail light lenses, stationary window seals, etc.

Drown that *****, and look for leaks.....

Thanks guys, I definitely do not plan on buying new carpet until I am 100% sure there are no other places leaking, I have a really good pressure washer, so when the time comes that I remove the carpet, I'll scrub it down, and rinse it off, then let it thoroughly dry before trying to reuse it, if I cannot reuse it then and only then will I get new carpet.

I do not have a sunroof, so my main concerns will be making sure the trunk leak is now fixed, and checking to see if water is getting in from the window/door areas, and I'll see if I can see anything on the front windshield leaking, as best I can anyway, I am not trying to have to tear the dash apart top remove it, hopefully that would only be necessary if all other areas show no leaks, and I still have water coming in, if that is the case it would have to be under the wiper cowl/firewall somewhere...
I did not think about the butyl tape holding the plastic sheet behind each door panel, I'll have to look into that as well.

As for the headliner, I really think the fact that I had so much water coming in, and the summer days got so hot, that the water started to condensate and effect the glues bond to the headliner board.
I could be wrong, but I am sure it had to at least aid in whatever the cause was.
I have had to use a temp method of keeping it from coming down altogether, so I don't think I'll be able to reuse the fabric, given the fact that it has several holes in it from screwing in the dorman headliner pins...

Again, thanks for the help!

Finally rained for a whole day, I open the trunk and find more water in it then was getting in when the seal was put in incorrectly.
I can see the main areas, which are the corners that were beat on a bit years back when I had a custom speaker box made/installed.
I'm going to try to put a bad around the lower lip that is where it goes on the trunks lip, and possibly readjust the trunk a little, it may be too tight, or not tight enough.
It is hard tp get it exactly like it was unless I replace the trunk pull down motor, which I did once before, and it only made it a little over a year.

If all else fails I am going to get a tarp, or install bilge pumps, lol

You are not kidding, I am thinking I may need to invest in some scuba gear if I don't get this fixed soon!

I went out earlier and pulled the weatherstrip off, gave the two problem areas a little more TLC with my 5lb mallet, and gave it a little pounding, then put a bead of SikaFlex on the trunks metal lip that it goes onto, then put the weatherstrip back, then ran a bead around the outside lip.
If that does not work I don't know what I am going to do, all else that I can try is adjusting the trunk a little, I think I have it as tight as it can close, I could probably adjust it a tiny bit so it is not squishing the weatherstrip as much..

I have looked for car covers, none are really waterproof, the best way would be to throw a cheap car cover on it to keep the pain from getting scratched by a tarp, then throw a tarp over it..
Once I get this job it may be a pain when it rains, as it would look funny parked in a lot with a tarp over it, then what would I do with a soaking wet tarp, lol
