Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery if electrical components will be removed.

2. Inspect and Replace Seals

Tools Required: Screwdriver set, trim removal tools, adhesive sealant
Remove door panels carefully using trim tools to avoid damage.
Inspect the rubber seals around doors and windows. If damaged, replace with OEM parts.
Apply adhesive sealant to areas where the seal meets the body if needed.

3. Clear Sunroof Drains

Tools Required: Compressed air or a flexible wire
Locate the sunroof drain tubes (typically found at the corners of the sunroof).
Use compressed air to blow through the drain tubes to remove any clogs.
Verify that water flows freely out of the drain openings under the vehicle.

4. Check Windshield Seal

Tools Required: Utility knife, adhesive sealant, caulking gun
Inspect the windshield seal for gaps or deterioration.
If found, carefully cut away the old sealant and apply new adhesive sealant around the edges of the windshield.

5. Clean Undercarriage Drainage Holes

Tools Required: Hose or water source, inspection mirror
Locate drainage holes in the undercarriage, typically near the wheel wells and under the engine bay.
Use a hose to flush out any debris blocking these holes, ensuring proper drainage.
