Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface.
Disconnect the battery as a safety precaution.

2. Inspect and Clear Sunroof Drains

Locate the sunroof drain tubes, which are typically at the corners of the sunroof.
Use a vacuum or compressed air to clear any blockages.
Verify that the drains are functioning by pouring a small amount of water into the sunroof channel.

3. Check and Replace Door Seals (if necessary)

Inspect the door seals for any cracks or gaps.
Remove the old seals using a trim removal tool.
Clean the surface where the new seal will adhere.
Apply new weather stripping, ensuring it fits snugly.

4. Inspect and Reseal Windshield

Check the windshield seal for any visible damage.
If a leak is detected, remove the trim around the windshield.
Clean the area and apply a high-quality windshield sealant.
Replace the trim after the sealant has cured.

5. Clear HVAC Drain Line

Locate the HVAC drain line, usually found underneath the vehicle.
Inspect for clogs and remove any debris.
If necessary, use a flexible wire or pipe cleaner to clear the drain line.

6. Check Heater Core for Leaks

Inspect the heater core hoses for any signs of leakage.
If the heater core is leaking, it will need to be replaced.
Drain the coolant, remove the dashboard, and replace the heater core as per manufacturer guidelines.
