Solution

1. Preparation

Gather tools and parts necessary for the repair, including replacement seals if needed.
Ensure the vehicle is parked on a level surface and the interior is dry.

2. Inspect and Repair Door Seals

Tools Required: Flathead screwdriver, adhesive sealant (if applicable)
Remove any visible dirt or debris from the door seals using a cloth.
Check for any damage, and replace the seals if necessary by carefully prying off the old seal and applying the new one.

3. Clear Sunroof Drains (if applicable)

Tools Required: Compressed air or flexible wire
Locate the sunroof drain tubes, which can typically be found at the corners of the sunroof tray.
Use compressed air or a flexible wire to clear any blockages in the drain tubes.

4. Check Windshield and Rear Window Seals

Tools Required: Utility knife, adhesive sealant
Inspect the seals around the windshield and rear window for gaps or deterioration.
If damaged, carefully cut away the old sealant and apply new automotive-grade adhesive sealant, ensuring a watertight fit.

5. Clean Drainage Channels

Tools Required: Hose, soft brush
Locate drainage channels under the hood and near the cowl area.
Clear any debris using a soft brush and flush the channels with water from a hose to ensure proper flow.
