Solution

1. Preparation

Tools Required: Flashlight, hose, inspection mirror, towels, bucket
Gather necessary tools and materials for inspection and repair.
Park the vehicle on a flat surface and ensure it is in “Park” mode.

2. Inspect and Repair Door and Window Seals

Sub-steps:
1. Visually inspect the rubber seals around all doors and windows. Look for cracks, tears, or gaps.
2. If damage is found, remove the old seal using a trim removal tool.
3. Clean the surface where the new seal will be applied with isopropyl alcohol.
4. Install new seals according to manufacturer specifications, ensuring they are seated properly.

3. Clear Sunroof Drains

Sub-steps:
1. Locate the sunroof drain openings, typically found in the corners of the sunroof glass.
2. Use compressed air or a flexible cleaning tool to clear any debris or obstructions from the drain tubes.
3. Test drainage by pouring water into the sunroof channels and checking for flow from the drain openings underneath the vehicle.

4. Seal Trunk and Frunk

Sub-steps:
1. Inspect the rubber seals around the trunk and frunk for wear or damage.
2. Replace any deteriorated seals with OEM components.
3. Ensure the trunk and frunk close securely and that there are no gaps when latched.

5. Test Water Leaks

Sub-steps:
1. Use a hose to simulate rain by directing water over the areas previously identified as potential leak sources.
2. Observe the interior for any signs of water intrusion.
3. If leaks are detected, further isolate the source and repeat repairs as necessary.
