My 93, 96, and 01 all seem to suffer from the seam sealer failing and allowing water to make its way from the windshield drain to the floorboards.**
This can lead to issues like rusting floorboards, mildew or mold growth in the carpet, and excessive condensation inside the windshield.
My solution? Dump a can of Flex Seal in the windshield drain. It may seem unconventional, but this method is simple and effective.

Tools:
- Ramp or jack and jack stand
- Can of Flex Seal Liquid (32oz is more than enough, but 16oz may be cutting it close)
- Large-mouth funnel
- 5.5mm socket and ratchet
---
Instructions:
1. Remove both access covers to the drain.
2. Prep the area to your liking. For example, I unloaded a can of brake cleaner in the drain area and let it dry. This may not be the most effective cleaning method, but it’s better than nothing.
3. Raise the passenger side of the truck as high as possible.
4. Pour a good amount of Flex Seal into the middle access panel. I poured about 8 oz. The bigger the slug of Flex Seal, the more coverage and faster it will travel down the drain.
5. Watch the access panel on the driver’s side. Once you see the Flex Seal run off the edge, lower the passenger side and raise the driver’s side.
6. Watch through the middle access holes as the Flex Seal runs back toward the passenger side. Add more Flex Seal as needed. I probably added another 8 oz.
7. After a short while, you’ll notice Flex Seal dripping on the ground behind the passenger tire. (Place some cardboard underneath to avoid a mess.)
8. Lower the driver side so the truck now sits level.
9. Reinstall the access hole covers.
10. Done

The Flex Seal takes some time to fully cure but skins over fairly quickly. Allow 24 hours before exposing it to water. I recommend doing this on a hot day so the Flex Seal flows more easily and cures faster.
This entire process can be done in under an hour. Since doing this, my carpet has stayed completely dry. Thanks for reading—hope this helps!
