What Causes Water Leakage in the Car Cabin?

[MacHazel]

It may be due to improper bonding of the windshield, leaving gaps, or inadequate welding of the metal panel beneath the wipers. Here is some related information: 1. Definition: Commonly known as car windshield washer fluid. It is a consumable item in car usage. High-quality car windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. 2. Function: Windshield washer fluid typically has wetting, penetrating, and solubilizing functions, thereby serving to clean and remove dirt. The presence of alcohol and ethylene glycol can significantly lower the freezing point of the liquid, thus providing antifreeze properties and quickly dissolving frost.
