Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked in a well-ventilated area.
Disconnect the vehicle from any power source if applicable.

2. Inspect and Replace Seals

Sub-steps:
1. Remove any interior trim panels if necessary to access seals.

4. Replace any damaged seals with OEM parts, ensuring a proper fit.
5. Reinstall any trim panels removed during the inspection.

3. Clear Drainage Systems

Sub-steps:
1. Locate the sunroof drains (typically found at the corners of the sunroof).
2. Use compressed air or a flexible cleaning tool to clear any debris from the drains.
3. Verify that water flows freely through the drainage system by pouring water into the sunroof well and checking for drainage at the bottom.

4. Repair Interior Damage
