Solution

1. Preparation

Gather necessary tools and materials: flashlight, towel, and hose or bucket of water.
Ensure the vehicle is parked on a level surface and the trunk is clear of items.

2. Inspect Weather Stripping

Remove the weather stripping from the trunk lid carefully.
Clean the area where the weather stripping sits to remove debris.
Inspect the stripping for cracks or tears; replace if damaged.

3. Check Trunk Lid Alignment

Close the trunk and visually inspect the alignment.
If misaligned, adjust the hinges or latch to ensure a tighter seal when closed.

4. Examine Tail Light Seals

Remove the tail light assembly if necessary (usually involves unscrewing bolts).
Inspect the gaskets for cracks or deterioration; replace if needed.
Ensure the tail light is reinstalled properly to seal against moisture.

5. Assess Drainage Channels

Locate drainage channels and holes around the trunk area.
Clear any debris using a soft brush or compressed air.
Ensure that water can flow freely through the channels.

6. Conduct Water Test

Using a hose or bucket, pour water over the trunk area systematically.
Have an assistant observe the trunk interior for any signs of water intrusion.
If leaks are detected, revisit previous steps to identify and rectify the source.
