Solution

1. Preparation

• Gather all tools and materials required for the repair.
• Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Door Seals

• Tools Required: Trim removal tool, adhesive, replacement seals.
• Remove the interior door panel using a trim removal tool.
• Inspect the door seal for any tears or degradation.
• If damaged, remove the old seal and clean the surface thoroughly.
• Apply adhesive and install the new door seal, ensuring a tight fit. Reassemble the door panel.

3. Clear Sunroof Drains

• Tools Required: Flexible wire or compressed air.
• Open the sunroof fully to access the drainage channels.
• Use flexible wire to clear any obstructions in the drainage tubes.
• Alternatively, use compressed air to blow through the drains to ensure they are clear.

4. Inspect and Repair Cabin Air Filter Housing

• Tools Required: Screwdriver set.
• Locate the cabin air filter housing, typically behind the glove compartment.
• Remove the cover and inspect for any signs of water intrusion.
• If the housing is cracked or improperly sealed, replace it with a new one.

5. Check Windshield Seal

• Tools Required: Trim removal tool, silicone sealant, replacement seal (if needed).
• Inspect the windshield seal for gaps or deterioration.
• If gaps are found, apply silicone sealant to create a watertight seal.
• Replace the seal if necessary, ensuring it is properly seated.

6. HVAC System Inspection

• Tools Required: Multimeter, flashlight.
• Access the HVAC system's evaporator housing and inspect for leaks.
• Check for any electrical issues using a multimeter.
• If water is pooling inside the HVAC, replace any faulty components or seals.
