    Hey all, I finally found the source of my massive water leak! Ever since I’ve owned this car (bought it for $875 from a copart auction, see my thread) the car kept fogging badly and getting a bad musty smell. I would ozone it only for the smell to return.

    Finally last week I removed all the trunk trim. My battery was submerged entirely in water and water had spilled into the spare tire! I drained it all out with a shop vac.

    Two weeks later? Battery was half submerged again from rain! I popped the roof trim/seal up and sure enough tons of body cracks.

    For $5.19 at truevalue I bought some cheap caulk and slapped it all over the cracks with my finger. We’ll see if that holds!


    NOTE: cracks were present on both sides of the car!

    Here’s pics:

    Thanks for this post and the pictures. My car's hinge area was okay, but for other readers, also check the rear brake light assemblies. I think mine were allowing water under/into them. Also there are little horizontal weld/crease/metal joints on the inside of the car, bumper area facing forwards on both well sides (mine was wettest into the battery area). I used similar caulk to caulk where I could clearly see water dripping in. That plus caulking where the light assembly plastic presses up against the hatchback drain area has kept the battery and first aid well sides of the car dry. If you still get water, check the wheel well to battery well wall and make sure that's tight.
