Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure it is turned off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Door Seals

Tools Required: Trim removal tool, adhesive (if necessary)
Remove the door panel using a trim removal tool to access the inner seal.
Inspect the rubber door seal for damage or deterioration.
If damaged, carefully peel off the old seal and clean the surface.
Apply the new seal in place, ensuring it adheres properly.

3. Check and Reseal Windshield/Rear Window

Tools Required: Windshield sealant, utility knife
Inspect the edges of the windshield and rear window for gaps or cracks.
If gaps are found, use a utility knife to clear away any old sealant.
Apply new windshield sealant evenly around the edges and press down firmly.

4. Clean Sunroof Drains (if applicable)

Tools Required: Compressed air or flexible wire
Open the sunroof and locate the drainage holes in each corner.
Use compressed air or a flexible wire to clear any blockages from the drains.
Test the drainage by pouring a small amount of water into the sunroof channel and ensuring it flows freely out of the drains.

5. Inspect Cabin Air Filter Area

Tools Required: Screwdriver set
Remove the cabin air filter cover, typically located behind the glove box.
Check for any signs of water intrusion or debris.
Replace the cabin air filter if it appears wet or damaged.

6. Clear Underbody Drainage Holes

Tools Required: Hose or compressed air
Locate the drainage holes on the underbody of the vehicle.
Use a hose or compressed air to clear any debris that may be clogging the holes.
