    2002 STS trunk leak

    I recently bought a 2002 STS. I live in an area with a lot of rain fall. My trunk was leaking and had built up a lot of water. I have since re-glued and set all the trunk rubber seals. Still am getting a small amount of water coming into the trunk from somewhere. Has anyone else experienced this issue? Any ideas on other trouble areas that may need re-sealed? Thanks in advance!

    EVERYONE has experience this. It was a standard feature. Check the body seams and the tail light seals.

    I just had a bout with that issue and my problem was the lip on the trunk seal that is on the body side was letting water in behind the seal lip where it contacts the body metal and would travel down the channel between the trunk seal and the lip, when it reached a vertical area it would flow around the trunk lip into the trunk
    I put a bead of loc-tite gasket maker from a pressurized can all the way across the top and down both sides to below the vertical area and now no leaks.

    Mine was a leaky quarter panel seam.

    Here you go - and this only scratches the surface - take out "2002" and do a search again - more and more.

    There's also a ton of info on your Seville Seville Touring Sedan down in Cadillac Tech Tips.

    Re: 2002 STS trunk leak

    The cure I've found and used on many of these cars, has been to remove and reseal the trunk weatherstripping adhesive at the bottom and cut a small hole in each outside edge at the bottom corner of the seal. Strangely, there are little holes in the weatherstripping's flawed design, which face somewahat inward and the seal fills with water and then dumps it into the trunk spare tire well.

    With this fix, as the seal fills up, it will will just drain out the the two holes and down each side of the bumper. I've fixed about six 98-04 Sevilles like this already and the trunks all stayed bone dry afterwards. The new updated seal from GM had the hole positions moved to avoid this, so buying the revised one is also an option.

    Thank you for the info! I ended up drilling a small hole in the spare tire wheel well. I then removed all seals and glue. Re-glued and sealed. Also sealed the top edge closest to the back window. No leaks yet, hoping to stay that way!
