Solution

1. Preparation

Gather tools and materials:
- Torx or Phillips screwdriver
- Silicone sealant or trunk weatherstrip
- Cleaning cloths
- Bucket or container for water testing
Ensure the vehicle is parked on a level surface and the trunk is empty.

2. Inspect and Repair Trunk Seal

Remove any debris from the trunk seal area to ensure proper adhesion.
If the seal is damaged, carefully pull it away from the trunk lip.
Clean the surface where the new seal will be applied using a cloth.
Apply a new trunk weatherstrip or silicone sealant along the trunk lip, ensuring it is evenly distributed and adheres properly.
Press the seal back into place and allow it to cure according to the manufacturer's instructions.

3. Check and Clean Drainage Channels

Locate the drainage channels in the trunk area, typically found near the tail lights or bottom edges.
Remove any dirt, leaves, or debris that may be blocking the drainage holes.
Use a small brush or compressed air to clear any stubborn blockages.
Test the drainage by pouring a small amount of water into the channels to ensure proper flow.

4. Inspect and Replace Tail Light Gaskets

Remove the tail light assembly using a screwdriver.
Inspect the gaskets for any signs of wear, cracks, or misalignment.
Replace the gaskets if they appear damaged and apply a small amount of silicone sealant around the edges before re-installing the tail light.
