Where Does the Gap in the Front Windshield Lead To?

[VanSerenity]

Generally, this gap is connected to the air conditioning vents because the air from the windshield defogging function comes out from here. Specific details are as follows: 1. Items falling in: If something falls into this gap, it will most likely end up at the air conditioning vent. If the item is very small, it might fall to the bottom of the air conditioning duct. Typically, items that fall in won’t damage any components; at worst, they might block the air deflector or cause noise while driving. Turn on the air conditioning and check the airflow—if there’s no impact or unusual noise, there’s usually no issue. 2. Avoid installing sealing strips: Installing a sealing strip would block the vent, rendering the defogging function ineffective. Additionally, much of the car’s noise comes from the internal engine, so installing sealing strips has minimal effect on noise reduction.
