What to Do When the Front Windshield Fog Cannot Be Blown Away?

[RiverRose]

If the fog on the front windshield cannot be blown away, it may be due to a leak in the glass interlayer seal, allowing water vapor to enter the windshield interlayer. Specific details are as follows: 1. Solution: Identify the leak in the windshield seal, blow out the water vapor from the windshield, and reseal the windshield. 2. Cause of fogging: Fogging on the front windshield can occur on the inside or outside. Whether internal or external, the main reason is that the glass surface temperature is lower than the air temperature, and the air humidity is relatively high. When warm, humid air encounters the cold front windshield, it releases heat and condenses, forming fog.
