Solution

1. Preparation

Tools Required: Flashlight, flathead screwdriver, water hose, vacuum, soft cloths.
Disconnect the vehicle battery for safety.
Ensure the vehicle is on level ground and the interior is dry.

2. Inspect Door Seals

Use a flashlight to visually inspect the rubber seals around each door.
If any seal appears cracked or damaged, carefully remove it using a flathead screwdriver.
Replace with OEM seals for proper fit.

3. Check Sunroof Drains

Open the sunroof and locate the drain holes (usually at the corners).
Use a water hose to pour a small amount of water into the drain holes.
Ensure water flows freely from the undercarriage; if not, clear any clogs with a flexible cleaning brush.

4. Examine Windshield Seal

Inspect the windshield for any gaps between the glass and the body of the vehicle.
If the seal is compromised, carefully remove the trim using a flathead screwdriver.
Apply a new bead of automotive sealant around the perimeter and press the windshield back into place.

5. Inspect HVAC Drain Tube

Locate the HVAC drain tube, typically found under the vehicle.
Check for clogs by gently squeezing the tube to see if any debris comes out.
If blocked, clear the drain tube using compressed air or a flexible cleaning rod.
