Volkswagen Jetta water leaks into the car during rain despite windshield replacement on Volkswagen Jetta

Some Volkswagen Jetta owners report experiencing water leaks during rain, even after windshield replacement. These leaks may be attributed to several factors, including issues with the cabin air intake seal, which can allow water to enter the vehicle. Additionally, blocked or malfunctioning sunroof drains can lead to water intrusion into the cabin. Deteriorated weatherstripping around the glass roof is another common cause, as it may permit water to flow down the A-pillar. Owners also note the importance of distinguishing between coolant and water under the vehicle, as coolant leaks can indicate different problems. Furthermore, leaking drain tubes can result in water seeping into the carpet, particularly around the A-pillar and sun visor attachments, and trimming these tubes may provide a solution. Regular cleaning of seals, weatherstripping, and drain tubes is recommended to prevent blockages and mold growth that could exacerbate these issues.
