Solution

1. Preparation

Gather necessary tools and materials.
Ensure the area is dry and clean for effective inspection.
Tools Required: Flashlight, water hose or bucket, towels for clean-up.

2. Inspect and Clear Drain Holes

Locate the sunroof drain holes, usually found in each corner of the sunroof frame.
Use a flexible wire or compressed air to clear any obstructions.
Ensure water flows freely through the drain holes by pouring a small amount of water into the sunroof tray and checking for drainage underneath the vehicle.

3. Replace Damaged Weather Stripping

Identify any sections of weather stripping that are cracked or missing.
Carefully peel off the old weather stripping using a trim removal tool.
Clean the surface to remove any adhesive residue.
Apply new weather stripping, ensuring a tight seal along the entire length.

4. Reseal Windows and Windshield

Inspect the adhesive around windows and windshields for any gaps.
If gaps are found, carefully remove old sealant using a utility knife.
Clean the area thoroughly to ensure good adhesion.
Apply new sealant, using a caulking gun, to fill any gaps and ensure a watertight seal.

5. Check and Repair Interior Components

Remove any wet carpeting or mats to allow for drying and inspection.
If the padding underneath is wet, consider replacing it to prevent mold growth.
Use a wet/dry vacuum to remove excess water from the interior.
