Solution

1. Preparation

Tools Needed: Flashlight, water source, small funnel, towels for drying, and dielectric grease.
Safety Warnings: Ensure the vehicle is parked on a level surface and the engine is off before beginning the inspection.

2. Inspect Door Seals

Sub-steps:
1. Open all doors and visually inspect the rubber seals for any visible damage.
2. Run your fingers along the seals to feel for any breaks or gaps.
3. Apply dielectric grease to the seals to enhance water resistance if necessary.

3. Check Sunroof Drains

Sub-steps:
1. Open the sunroof fully.
2. Use a funnel to pour water into the sunroof channel.
3. Observe if water drains out through the exterior drain holes (usually located near the wheel wells).
4. If clogged, use a flexible cleaning tool or compressed air to clear the drain.

4. Examine Window Seals

Sub-steps:
1. Inspect the seals around each side window for tears or misalignment.
2. Adjust or replace any seals that do not provide a tight fit.
3. Clean the area around the seals to ensure good adhesion for any sealant.

5. Check Firewall and Grommets

Sub-steps:
1. Open the hood and visually inspect the firewall where wiring and hoses pass through.
2. Look for any missing or damaged grommets that could allow water to enter.
3. Replace any faulty grommets with new ones and seal with silicone if needed.

6. Test Drainage Channels

Sub-steps:
1. Inspect the drainage channels at the base of the windshield for debris.
2. Clear any leaves or dirt that may block the water flow.
3. Pour water along the channels to ensure it drains properly to the ground.
