Solution

1. Preparation

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

2. Inspect Cabin Air Filter

Tools Required: Screwdriver, vacuum cleaner
Remove the cabin air filter cover using a screwdriver.
Take out the cabin air filter and inspect for signs of moisture or mold.
Clean the area with a vacuum cleaner if debris is present.
Replace the cabin air filter if it shows signs of damage or mold.

3. Check Seals

Tools Required: Silicone sealant (if needed)
Inspect the door and window seals for cracks or tears.
If any seals are compromised, clean the area and apply silicone sealant to ensure a water-tight seal.
Ensure all windows and doors close properly.

4. Inspect Windshield and Rear Window

Tools Required: Water spray bottle
Use a water spray bottle to simulate rain and check for leaks around the windshield and rear window.
If leaks are found, consider resealing using appropriate windshield adhesive.

5. Examine Sunroof Drainage

Tools Required: Compressed air or flexible tubing
Locate the sunroof drainage tubes and check for blockages.
Use compressed air or flexible tubing to clear any obstructions.
Verify that water drains freely from the sunroof area.

6. Verify Air Conditioning Drain

Tools Required: None
Start the vehicle and run the air conditioning on high.
Check underneath the vehicle for water dripping from the A/C drain tube.
If no water is present, inspect the drain tube for blockages and clear them if necessary.
