What are the causes of water ingress in the 2011 Lavida?

[VanSophie]

Here are the reasons for water ingress in the Lavida: 1. Sealing strip issue: Check if the door sealing strips are aged or cracked, as poor sealing can also lead to external water penetration. 2. Waterproof plastic sheet problem: The Lavida's door waterproof design relies solely on a waterproof plastic sheet inside the door panel. If the door has been disassembled or reassembled, it can easily cause leaks. To address this issue, the waterproof plastic sheet can be replaced. 3. Sunroof and drainage hole problem: Check if the sunroof and door drainage holes are blocked. Break a chopstick and use the pointed end to poke the drainage holes under the door to clear them. 4. Air conditioning drainage problem: Internal water leakage may also be caused by air conditioning drainage entering the car. Air conditioning drainage failure is mainly due to clogged air conditioning drainage outlets, preventing water from being discharged outside the car and causing it to overflow into the car through gaps in the evaporator box. For this phenomenon, it is necessary to take the car to a repair shop for technicians to diagnose and troubleshoot the issue.
