Reasons for Water Leakage on One Side of the Car Cabin

[KinsleyLee]

Reasons for water leakage in the car cabin are as follows: Sealing Issues: The sunroof panel is uneven in height, the left and right gaps do not meet the manufacturer's standards, or the sunroof is incorrectly positioned, leading to severe sealing problems. Additionally, if the sunroof panel is not fully closed or left open, it can cause water leakage in the cabin ceiling. Corrosion Issues: After collision repairs to the car roof, if rust prevention is not properly handled, severe corrosion of the roof steel plate or the edges of the sunroof frame can result in water leakage in the cabin ceiling. Sunroof Drainage System Problems: The sunroof drainage system mainly consists of drainage channels, drainage pipes, and drain valves. The sunroof is not completely sealed, allowing a small amount of water to seep in and flow into the drainage channels, which can overflow. A small amount of water seepage is normal, but issues such as cracked sunroof drainage channels, detached, folded, broken, twisted, or blocked drainage pipes, poor routing, or clogged sunroof drain valves can all cause water leakage in the cabin ceiling.
