Solution

1. Preparation

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

2. Inspect and Clear Sunroof Drains (if applicable)

Locate the sunroof drain tubes, typically at the corners of the sunroof.
Use a soft, flexible wire or a compressed air canister to clear any obstructions in the drain tubes.
Test the drains by pouring a small amount of water into the sunroof channel and ensuring it flows out underneath the vehicle.

3. Check and Replace Door Seals

Inspect the door seals for cracks or wear.
If damaged, remove the old seals by carefully prying them off with a trim removal tool.
Clean the surface where the new seals will be applied.
Install new door seals, ensuring they are properly seated and aligned.

4. Heater Core Inspection

Check for wetness in the passenger side footwell.
If wet, remove the dashboard or trim panel to access the heater core.
Inspect the heater core for leaks; if necessary, replace it by disconnecting the heater hoses and unbolting it from the housing.

5. Coolant System Inspection

Inspect the radiator and hoses for signs of leaks.
If a leak is found, replace the damaged hose or radiator.
Refill the cooling system with the appropriate coolant type.
