Solution

1. Preparation

Gather necessary tools and materials.
Disconnect the battery if any electrical components will be accessed.

2. Inspect and Replace Weather Stripping

Tools Required: Trim removal tool, adhesive.
Remove old weather stripping by prying it off carefully.
Clean the surface where the new weather stripping will be applied.
Measure and cut the new weather stripping to fit the door or window frame.
Apply the new weather stripping and press firmly to ensure a good seal.

3. Clear Sunroof Drains

Tools Required: Flexible wire or compressed air.
Locate the sunroof drain tubes, typically at the corners of the sunroof.
Use flexible wire to gently clear any blockages.
Alternatively, use compressed air to blow out debris from the drain tubes.

4. Reseal Windshield

Tools Required: Windshield sealant, scraper, and cleaning cloth.
Inspect the windshield seal for gaps or damage.
If necessary, carefully remove the old sealant using a scraper.
Clean the area thoroughly, then apply new windshield sealant evenly along the edge.
Press down gently to ensure proper adhesion and seal.

5. Inspect Cabin Air Filter Area

Tools Required: Screwdriver (if applicable).
Remove the cabin air filter cover and check for any signs of water intrusion.
If water is present, inspect the area for clogged drain holes or improperly sealed components.
Clean the area and ensure all seals are intact.
