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 to avoid any electrical issues.

2. Inspect Door Seals

Remove the door panel if necessary using a trim removal tool.
Inspect the rubber seals for cracks or tears.
Replace any damaged seals with OEM (Original Equipment Manufacturer) parts.
Reattach the door panel securely.

3. Check Windshield Seal

Examine the perimeter of the windshield for gaps.
If the seal is compromised, carefully remove the windshield using a windshield removal tool.
Clean the bonding surface and apply fresh adhesive.
Reinstall the windshield and allow it to cure as per the adhesive manufacturer’s instructions.

4. Inspect Sunroof Drains

Open the sunroof and locate the drain holes (usually at the corners).
Use a thin, flexible wire or compressed air to clear any blockages.
Test the drains by pouring water into the sunroof opening and ensuring it flows out underneath the vehicle.

5. Clear HVAC Drainage System

Locate the A/C drain line under the vehicle.
Check for clogs by removing any debris.
If necessary, use compressed air to blow through the drain line and clear it.

6. Seal Body Seams

Inspect the body seams for rust or gaps.
Clean the area and apply automotive sealant to any exposed seams.
Allow the sealant to cure fully before exposing to moisture.
