Solution

1. Preparation

Gather tools and materials: vacuum, towels, moisture absorber (like silica gel), and replacement parts as needed.
Ensure the vehicle is parked in a dry, well-ventilated area.

2. Inspect and Replace Weather Stripping

Sub-steps:
1. Remove any visible trim or panels to access the weather stripping.
2. Carefully peel off the old weather stripping using a trim removal tool.
3. Clean the surface with isopropyl alcohol to ensure proper adhesion.
4. Measure and cut the new weather stripping to size.
5. Press the new weather stripping firmly into place along the door and window edges.

3. Check and Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter access panel (usually behind the glove box).
2. Remove the panel using a screwdriver or trim tool.
3. Pull out the old cabin air filter and check for moisture or mold.
4. Install a new, dry cabin air filter, ensuring it fits securely.
5. Reattach the access panel.

4. Clear Drainage Channels

Sub-steps:
1. Locate the sunroof drains (usually at the four corners of the sunroof).
2. Use a flexible wire or compressed air to clear any blockages.
3. Pour a small amount of water into the drain to ensure proper flow.

5. Inspect and Seal Windows

Sub-steps:
1. Check the windshield and rear window for proper sealing.
2. If any gaps are found, apply a suitable automotive sealant.
3. Allow the sealant to cure as per manufacturer's instructions.
