2. Inspect and Replace Door Seals

Sub-steps:
1. Open the door and visually inspect the seals for cracks or separation.
2. Run your finger along the seal to feel for any gaps.
3. If damaged, remove the old seal by gently pulling it away from the door frame.

5. Install the new seal, ensuring it fits snugly and evenly.

3. Clear Sunroof Drains

Sub-steps:
1. Open the sunroof fully.
2. Locate the sunroof drain holes at the corners.
3. Use a compressed air tool or a flexible wire to clear any blockages.
4. Pour a small amount of water into the drain holes to ensure flow is unobstructed.

4. Inspect Windshield Seal

Sub-steps:
1. Look for any gaps or visible damage around the windshield.
2. If the seal is loose, carefully pry it up and clean the area beneath.
3. Apply a suitable automotive sealant and press the seal back into place.
4. Allow the sealant to cure as per the manufacturer's instructions.

5. Check Rear Hatch Seal

Sub-steps:
