Solution

1. Preparation

Gather the necessary tools and parts. Ensure the vehicle is parked on a flat surface.
Tools Required: Flashlight, water hose, towels, vacuum (for cleanup).

2. Inspect Door Seals and Weather Stripping

Visually inspect the door seals for cracks or tears.
Use a flashlight to check for gaps where water could enter.
If damaged, remove the old weather stripping and clean the surface before applying new adhesive weather stripping.

3. Check Sunroof Drains

Open the sunroof and locate the drain holes at the corners.
Use compressed air or a flexible wire to clear any blockages.
Pour a small amount of water into the sunroof channel and verify it drains properly.

4. Examine Windshield and Rear Window Seals

Closely inspect the seals around the windshield and rear window for any signs of wear or gaps.
If any damages are found, remove any old adhesive and apply a new sealant or replace the window.

5. Inspect HVAC System Drain

Locate the drain tube underneath the vehicle, typically near the passenger side.
Ensure it is not clogged. Clean it out using compressed air if necessary.

6. Clean Up and Final Checks

After repairs, dry any wet areas thoroughly to prevent mold growth.
Use a vacuum to remove any debris or moisture from carpets and upholstery.
