my Skoda Octavia NFL (2020-Present) has condensation inside, how to fix it?

Solution

1. Preparation

• Gather all necessary tools and materials.
• Ensure the vehicle is parked in a well-ventilated area.
• Disconnect the battery if working on electrical components.

2. Inspect and Replace Weather Stripping

• Tools Required: Trim removal tool, utility knife, adhesive sealant.
• Remove the existing weather stripping carefully to avoid damage.
• Clean the surface of the door frame where the weather stripping will be applied.
• Cut the new weather stripping to the appropriate length and apply adhesive as needed.
• Press the new weather stripping into place firmly and ensure a proper seal.

3. Check and Replace Cabin Air Filter

• Tools Required: Screwdriver or socket set (depending on vehicle design).
• Locate the cabin air filter housing, usually behind the glove compartment.
• Remove the screws or clips holding the cover in place.
• Take out the old filter and inspect it for dirt and moisture.
• Install a new cabin air filter, ensuring it is oriented correctly as per the airflow direction marked on the filter.

4. Clear Sunroof Drains (if applicable)

• Tools Required: Flexible wire or drain cleaning tool.
• Locate the sunroof drain tubes, usually at the corners of the sunroof.
• Insert the flexible wire into the drain tubes to clear any blockages.
• Run water through the drains to ensure they are flowing freely.

5. Inspect and Reseal Windshield and Rear Window

• Tools Required: Windshield sealant, razor blade, cleaning cloth.
• Inspect the perimeter of the windshield and rear window for gaps or peeling sealant.
• Use a razor blade to remove any old sealant if necessary.
• Apply a new bead of windshield sealant evenly along the edge, ensuring no gaps remain.
