Solution

1. Preparation

Gather tools and materials: towels, flashlight, hose, and cleaning supplies.
Park the vehicle on a level surface and turn off the engine.

2. Inspect and Replace Door Seals

Examine the rubber seals around all doors for cracks or gaps.
If damaged, remove the old seal using a trim removal tool.
Clean the area where the seal attaches to ensure proper adhesion.
Install new seals by pressing them firmly into place, ensuring they fit snugly.

3. Clear Sunroof Drainage System

Locate the sunroof drainage tubes (typically at the corners of the sunroof).
Use compressed air to blow out any debris from the tubes.
Ensure that the tubes direct water away from the interior and are not pinched or blocked.

4. Clean HVAC Drain

Locate the HVAC drain tube, usually found underneath the vehicle near the firewall.
Use a flexible wire or a vacuum to remove any blockages.
Pour a small amount of water down the tube to ensure it flows freely.

5. Verify and Seal Any Leaks

Use waterproof sealant to seal any gaps or cracks found during inspections.
For larger gaps, consider using a patch or additional sealing materials.
Allow any sealant to cure as per manufacturer's instructions before testing for leaks.
