Solution

1. Preparation

Gather tools and materials: flashlight, hose, towels, and sealant as needed.
Ensure the vehicle is parked on a flat surface and allow time for any existing water to dry.

2. Inspect and Repair Windshield/Window Seals

Use a flashlight to examine the seals for cracks or separation.
If damaged, gently remove the old sealant using a scraper and clean the surface.
Apply new automotive sealant to the affected areas and allow it to cure as per manufacturer's instructions.

3. Check and Replace Door Seals

Open each door and visually inspect the rubber seals for wear or tears.
If any seals are compromised, remove them carefully.
Install new door seals by pressing them into the designated grooves until secure.

4. Clear Sunroof Drains

Locate the sunroof drainage tubes (usually found at the corners of the sunroof frame).
Use compressed air or a flexible wire to clear any blockages in the tubes.
Test the drainage by pouring water into the sunroof and ensuring it drains correctly.

5. Inspect Heater Core

Check for signs of coolant leaks or dampness near the passenger side floor.
If a leak is detected, drain the coolant, remove the heater core, and replace it with a new unit.
Refill the coolant system and bleed any air from the system.
