Will the sunroof not leak if it is not opened?

Not opening the sunroof does not necessarily prevent leakage, as aging seals can also cause leaks. Below is an introduction to the advantages of a car sunroof: Cooling: Utilizing the negative pressure formed on the roof during vehicle movement to extract hot air can achieve rapid ventilation and cooling. This method is 2-3 times faster than using the car's air conditioning for cooling. Ventilation: When the car is moving at high speed, air flows quickly around the vehicle. Opening the sunroof creates a negative pressure zone outside the car, which, due to the difference in air pressure inside and outside, helps extract stale air from the cabin, maintaining fresh air inside. Auxiliary defogging: Keeping the side windows closed while driving increases the temperature difference between the inside and outside of the car, leading to fog formation on the front windshield. Although most cars are equipped with anti-fog devices, some may not be very effective. Simply opening the sunroof to the rear-ventilation position can easily eliminate fog on the front windshield, ensuring driving safety.
