Is it normal for water to drip from the edges of the sunroof?
1 Answers
It is normal for the sunroof seal to have slight water seepage. If the sunroof seal is severely damaged, excessive water ingress may occur, and if the drainage pipe cannot discharge it in time, it may overflow into the cabin. In such cases, it is necessary to visit a 4S shop to check the cause of the fault and carry out repairs. Below is an introduction to sunroof leakage issues: 1. Dust and debris inside the sunroof track: The sunroof drainage pipe gets clogged, and excessive rainwater cannot be drained, seeping into the cabin through the sunroof waterproof seal. This issue can usually be resolved by using a thin wire to unclog the drainage pipe. 2. Deformation of the sunroof sliding track: Track deformation is generally caused by movement obstruction, where the motor forces the track to move back and forth, causing it to stretch and deform. This results in the sunroof glass not closing properly, allowing rainwater to enter the cabin. If there are no separate track components available, the entire sunroof frame assembly must be replaced. 3. Breakage of the sunroof lift arm: When the sunroof slides to the front and closes, if the lift arm is broken, the sunroof cannot rise to be flush with the roof, creating a depression. Rainwater then leaks into the cabin along the edges of the sunroof. This also requires replacing the entire frame assembly to resolve. 4. Aging of the sunroof waterproof seal: Especially in vehicles over 10 years old, the aged seal cannot form a tight seal with the roof, allowing rainwater to seep into the cabin. The solution is to replace the roof seal or the sunroof glass with a new seal.
