How to Deal with Water Leakage from the Car A-Pillar?

[Sienna]

Here are the steps to handle water leakage from the car A-pillar: 1. Sunroof: The sunroof drain holes are prone to blockage by branches, leaves, or dust. If the A-pillar is leaking, check if the sunroof drain holes are clogged or if there are any foreign objects in the sunroof tracks. Remove any debris if found. If the sealing strip is aged or deformed, it needs to be replaced. 2. Windshield: If the leakage occurs after windshield replacement due to uneven sealant application, the windshield should be removed and reinstalled with proper sealant. 3. Windows and roof rack mounting holes: Inspect the sealing strips around the windows and the mounting holes of the roof rack. Replace any aged sealing strips as necessary.
