Where is the drainage hole for the windshield?

The drainage hole for the windshield is located below the wiper linkage. Here is some relevant information about the drainage hole: 1. Concept: The vehicle drainage hole is the outlet that drains accumulated water from the vehicle during rainy weather. Generally, vehicle drainage holes are located in the following areas: the front windshield area of the engine compartment, the four corners inside the sunroof, the lower part of the front and rear doors, inside the fuel tank cap, at the bottom of the spare tire in the trunk, and the gaps between the front and rear headlights and the body fenders. 2. Precautions: There is usually a drainage hole below the fuel tank cap. If it gets clogged, water may accumulate in the fuel tank during car washes or rainy weather, potentially damaging the fuel tank. The spare tire in the trunk is generally located in a relatively low part of the vehicle body. When driving through waterlogged areas, if the water level rises above the headlights, water may seep in and reach the interior of the vehicle. The drainage holes in this area are rarely used.
I found that the drainage holes for the front windshield are usually located in the plastic trim panel beneath the windshield, specifically under the wiper arms or along the gaps near the hood edge. These small holes are designed to drain rainwater, preventing water accumulation inside the cabin or engine compartment. I once experienced a clogging issue when leaves and dust blocked the holes, causing water to back up into the footwell area and nearly damaging the car's electrical system. Therefore, it's essential to inspect them regularly and use a soft brush or a blower to clear debris, especially before the rainy season. If water accumulates excessively, it could corrode the body panels or lead to mold growth in the AC system. Every time I wash my car, I take a quick look at those holes to ensure they're clear. In short, this is a small but crucial maintenance detail that affects driving safety.
In my years of driving experience, the drainage holes for the windshield are actually hidden in the plastic deflector channel at the bottom of the windshield, usually near the A-pillars at both ends. These holes are small and can easily get clogged by twigs or mud. Once blocked, rainwater accumulates around the windshield. I never overlook this because the accumulated water can flow into the firewall area, causing the car's floor to get soaked or leading to short circuits in electronic components. The cleaning method is simple: just open the hood, locate the deflector channel, and gently pull out the debris with a small hook. I also recommend checking monthly to ensure the deflector channel is properly angled, as smooth water flow can prevent unpleasant odors. Although this task is minor, doing it well can save you from major repairs.
The windshield drainage holes are located along the lower edge of the windshield, specifically on the plastic trim panel beneath the hood. As a new driver, I once encountered clogging issues where rainwater leaked into the cabin. When cleaning, avoid using sharp tools to poke the holes to prevent damaging the plastic. Maintaining clear drainage is crucial to prevent water accumulation that could damage the vehicle or impair visibility. Now I inspect them seasonally.
