Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery if working with electrical components.

2. Inspect Door Seals

Remove any trim panels to access door seals.
Clean the seal area with a soft cloth and inspect for cracks or tears.
If damaged, replace seals using appropriate adhesive or clips.

3. Check Windshield and Rear Window Seals

Inspect the bonding of the windshield and rear window for gaps or peeling.
If necessary, reseal using automotive adhesive or consult a professional for replacement.

4. Clear Sunroof Drains

Open the sunroof fully to access the drain points.
Use a flexible wire or compressed air to clear any blockages in the drain tubes.
Test the drains by pouring water into the sunroof channel and ensuring it drains outside the vehicle.

5. Inspect Cabin Air Filter Housing

Remove the cabin air filter cover.
Check for any water entry points or damage in the housing.
Replace the cabin air filter if it is wet or damaged.

6. Check HVAC Components

Inspect for leaks around the evaporator core and heater core.
If moisture is present, consider replacing the affected components.

7. Review Underbody and Wheel Well

Inspect for signs of rust or damage that could allow water ingress.
Treat any rust spots and apply a protective coating if necessary.
