Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the battery to prevent any electrical issues.

2. Clean and Clear Drainage

Use compressed air or a flexible wire to clear any blockages in the sunroof drains.
Ensure that all drainage paths are free of debris.

3. Replace Weatherstripping

Remove the old weatherstripping from doors and windows using a trim removal tool.
Clean the surface area where the new weatherstripping will be applied.
Install new weatherstripping by aligning it properly and pressing it into place.
Ensure a tight seal by checking for any gaps.

4. Reseal Windows

Carefully remove the existing sealant from the windshield/rear window using a razor blade scraper.
Clean the surface thoroughly with a solvent to remove any residue.
Apply a suitable automotive silicone sealant around the edges of the windshield or rear window.
Allow the sealant to cure as per manufacturer instructions.

5. Inspect and Repair Underbody

Inspect the underbody for rust, especially around the wheel wells and under the doors.
If rust is present, sand it down to bare metal and apply rust inhibitor.
Use undercoating to seal the affected areas.
