Solution

1. Preparation

Gather necessary tools: a flashlight, water hose, vacuum, towels, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Door Seals

Check each door seal for damage or wear.
If any seals are damaged, pry them off gently with a flathead screwdriver and replace them with new OEM seals.
Ensure that the new seals fit snugly against the frame of the door.

3. Check Windshield Seal

Examine the windshield for cracks or gaps in the seal.
If gaps are present, remove the windshield trim carefully using a flathead screwdriver.
Apply a quality automotive sealant along the edge of the windshield if necessary and press firmly to ensure a tight seal, or consult a professional for windshield replacement.

4. Clean Sunroof Drains

Locate the sunroof drains (usually in the corners of the sunroof opening).
Use a flexible wire or a vacuum to clear any debris from the drains.
Pour a small amount of water into the sunroof channel to ensure it drains properly.

5. Inspect Cabin Air Filter

Remove the cabin air filter cover, usually located behind the glove box.
Inspect the filter for dampness or debris.
Replace the filter if it is damp or dirty, ensuring the new filter is installed correctly.

6. Test HVAC Drainage

Locate the drain tube from the HVAC system, usually found under the vehicle.
Ensure it is not clogged by gently pushing a flexible wire into the drain tube.
Clear any blockages to allow proper drainage.
