What causes water leakage from the door into the interior of the Volkswagen Lavida?
2 Answers
The reason for water leakage from the door into the interior of the Volkswagen Lavida is either damage to the door waterproof plastic sheet or blockage of the air conditioning drain outlet. Below is a detailed analysis of the specific causes: Damage to the door waterproof plastic sheet: If the door waterproof plastic sheet of the Volkswagen Lavida is damaged and the door has been disassembled or reinstalled, it can easily lead to water leakage. The waterproof plastic sheet can be replaced. Additionally, it is necessary to check whether the door sealing strip is aged or cracked, as poor sealing can also cause external water to seep in. Blockage of the air conditioning drain outlet: Air conditioning drainage failure is mainly caused by a blocked air conditioning drain outlet, preventing water from draining outside the vehicle. This results in water overflowing from the gaps of the evaporator box into the interior. It is recommended to visit a repair shop for professional diagnosis and troubleshooting by maintenance personnel.
My old Lavida started leaking last year, which was a real hassle. The main issue was the aging and deformation of the door sealing strips, allowing rainwater to seep in through the gaps. Additionally, the drainage holes at the bottom of the doors were easily clogged by rotten leaves, causing accumulated water to backflow into the car. Once during a car wash, I noticed cracks in the fastener holes on the inner door trim panels, and water sprayed directly into the driver's seat through these holes. Eventually, I replaced all the sealing strips on the four doors and made it a habit to clean the drainage holes weekly, finally solving the leakage problem. The mechanic mentioned that cracked waterproof sealant at the door weld seams is also a common issue with Lavidas, and all these details need to be checked one by one.
