Solution

1. Preparation

Gather tools and materials: flashlight, towels, silicone sealant, replacement door seals (if needed), vacuum for debris.
Ensure the vehicle is parked in a dry area.

2. Inspect and Repair Door Seals

Inspect all door seals for wear or damage.
If damaged, remove old seals by peeling them off carefully.
Clean the surface where the new seal will adhere.
Apply silicone sealant to the surface and press the new door seal into place.
Allow the sealant to cure as per manufacturer instructions.

3. Check Windshield Sealing

Inspect the windshield for visible gaps or damage in the sealant.
If gaps are found, carefully remove any loose material around the windshield.
Apply new polyurethane sealant around the edges of the windshield, ensuring an even bead.
Allow the sealant to cure as specified by the product instructions.

4. Clear Sunroof Drains

Locate the sunroof drains (usually at the corners of the sunroof opening).
Use compressed air or a small flexible tool to clear any blockages in the drains.
Test the drains by pouring a small amount of water into the sunroof area and ensuring it drains properly.

5. Clean Cowl Area and Drainage

Remove any debris from the cowl area beneath the windshield wipers.
Ensure that the drainage channels are clear to allow for proper water runoff.
Use a vacuum to remove any leaves or dirt.

6. Verify HVAC Drainage

Inspect the area where the cabin air filter is located for any water accumulation.
Make sure the drain pan underneath the HVAC system is not clogged.
Clear any blockages and ensure that the drain hose is properly connected and functioning.
