Hi

My trunk leaks when we get a hard rain - the rubber gasket seal has a few little chunks out of it at the bottom near the latch area. Are there any known issues? Any hoses from the sunroof (which never is opened) or any other things to look at? Can I get a new gasket for the trunk or is there any patches?

2004 Concorde Limited 135,000 3.5l

Thanks in advance

so this problem is fixed?
No, the intrepid trunk seal apparently is not the same as the Concorde - and that I can not fine new or used. I am also not sure if that is even the cause of my problem. I get a little water in my trunk whenever it rains really hard. My folding bikes going in and out of the trunk have torn the bottom of the rubber gasket a little bit - maybe that has caused this leaking - but maybe not. Are there any drain hoses or other type things to check? Any advice on repairing my gasket seal? I can't find any - even used that aren't also torn. Are there universal gasket seals?

funny, it says concorde on top, intrepid on the bottom.
lhs would be the same, if it makes a difference looking it up.
maybe run some water around with the lid open and see if it can get under the gasket anywhere.
look for water stains at the top edge that look like maybe water is getting by.
maybe the seal is going around your rear window.
just throwing some things out there.
don't know if ours are hollow, if they are you might get something stuffed into low/flat spots.

As another person responded, the Mopar trunk lid weatherstripping may still be available as new, old stock on ebay if you want to search under the part number from the Parts Catalog for your year (pdfs in the Service Information subforums here). However, it will probably be quite expensive on ebay or from the online Mopar parts websites. So the best alternative is obviously to check a junkyard for one that is still good and not deteriorated. Some junkyards may even be able to order one from another junkyard if they are in a used parts network (be sure to give them your exact car year/model).

If you can't do that, there is a much less expensive solution, but takes a bit of careful work. Some of the better auto parts stores sell rolls of car weatherstripping in different cross-section shapes and sizes. You want the actual firm weatherstripping, and not the very squishy open-cell foam that they may also sell. Some NAPA and (few remaining) Car Quest stores may even have big rolls that they can cut to length. Take in a drawing of the trunk weatherstripping cross section (height x width) and approximate shape, to get the size you need so it will seal when the trunk clamps down. (They used to have a big paper catalog that showed the cross section shapes.) They do come in package rolls with different lengths, so you can only buy as much as you need to save money. Amazon does have it, but a lot of what they carry is cheapo imported junk that won't last, so I'd check the auto parts stores first.

To glue pieces of this in place, they also sell special car weatherstripping adhesive by Permatex, 3M, etc. It comes in yellow or black - get black or the yellow will show in the glued seam and look messy. It is like very strong contact cement (read instructions). It actually comes in regular and "super" types, with the super weatherstrip adhesive a bit stronger, so get that if they have it. You can search on weatherstripping adhesive on Amazon under automotive section to see the types/brands.

Then, if you have areas where the trunk weatherstripping is missing or deteriorated, you can cut these out with a sharp Xacto knife or box cutte) with some cardbord underneath (wear gloves). Then per the adhesive directions, carefully glue a replacement piece in place with adhesive on both the metal and the original weatherstripping on both sides so it won't leak through the glued seam. If you do it carefully, it will look OK. Also use a small amount of the weatherstrip adhesive to hold the original trunk weatherstripping in place on either side of the repair, and wherever it is loose around the trunk opening - feel all around and see if you can easily lift it up off the metal lip. Obviously, don't close the trunk down on it until the glue fully dry per the instructions - if the car is outside you can obviously use some rope to close the trunk lid most of the way down but not squish the weatherstripping.

Great advice - I will take a tape measure and some photos. I have a NAPA store in Bayonne NJ

UPDATE: Ok - I did find a deal on the OEM weather seal and it is the same as the intrepid - but before I order that a YouTube video got me looking elsewhere - there was some guy who swore 90% of all trunk leaks are caused by the tail light seals failing with age - I checked and mine are bad on close inspection - so I am going to try adding RTV since I have some - or black silicone call. Anyone ever hear of this being an issue with our cars?

only the threaded posts come through the back of ours
you undo 4? wingnuts and they pull out.
might have a little leak around the posts.
have to pull out the trunk trim and see if leaks through the openings.

is it while driving in the rain too?
could have a spot corroded out from underneath even.
you'll have to pull the trim to find it.
and pull the lights out and have a look behind.

Thanks for the help. I have only found moisture while it was parked - I would have to check when I have been driving in the rain. There is no rust on the underside of this car - none whatsoever. My jeep on the other hand is a rust bucket.

just a thought.
some hidden spot behind the wheel well.
just thinking of things to check.

if it's while standing, then it has to be from above.
pull the lights and have a look.
look on the underside of the trunk opening edges for water tracks.
might have to get help and lay in the trunk with a light and close the lid and have somebody run a hose around the opening.
should leak if the seal is bad anywhere.
look for tracks starting from around the rear window too, as drips can run along body panels before dropping.
