Why is there water in the car when it rains?
1 Answers
Possible reasons include leaks in the sunroof itself, poor sealing, or clogged/detached sunroof drainage holes preventing water from draining outside the vehicle. Below is relevant information: 1. Types of car sunroofs: Car sunroofs can be broadly categorized into: sliding-out, built-in, built-in flip-up, panoramic, and curtain styles. They are mainly installed on commercial SUVs, sedans, and other vehicle models. 2. Function of car sunroofs: Experts explain that air pollution inside vehicles seriously affects the health of drivers and passengers, especially after prolonged enclosure when harmful substances like benzene and formaldehyde from interior decorations accumulate in the cabin. Therefore, the first thing to do when entering the car after overnight parking is to open the sunroof, utilizing its superior negative-pressure ventilation principle to filter the cabin air and protect occupants' health.
