Sub-steps:
1. Remove the tail light assembly by unscrewing the mounting bolts and disconnecting the wiring harness.
2. Inspect the tail light gaskets for wear or damage; replace if necessary.
3. Reinstall the tail light assembly, ensuring a proper seal against the trunk.

4. Clear Drain Holes

Sub-steps:
1. Locate the trunk drain holes (usually found at the bottom of the trunk).
2. Use a small wire or compressed air to clear any debris blocking the holes.
3. Test the drainage by pouring a small amount of water over the area and ensuring it flows out properly.
