Why Can't the Car Window Be Fully Rolled Down?

[NorahFitz]

Car windows cannot be fully rolled down because the rear wheel arches occupy space in the rear doors, making the lower part of the door curved. This results in the lower part of the door being narrower than the upper part, leaving no space to accommodate the window glass when fully lowered, hence the window cannot be rolled down completely. Below is more information about car windows: 1. Types of car windows: Typically, car windows are divided into four types: front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. 2. Defogging car windows: (1) Slightly opening the window allows air circulation between the inside and outside of the car, maintaining consistent temperatures and preventing condensation on the inner surface of the windshield. (2) Turning on the air conditioning and adjusting the cabin temperature can eliminate fog on the windshield.
