The hole at the base of the wiper leads to the outside of the car. It primarily serves as a drainage channel to remove accumulated water during rain. If the vehicle is frequently parked outdoors, leaves, dirt, and other debris can accumulate in the drainage pipe. Excessive debris may clog the drainage hole, leading to water leakage into the car. Therefore, it is essential to clean these obstructions regularly during to ensure the drainage channel remains clear. Below is more information about wipers: 1. Wipers are devices designed to remove raindrops and dust from the vehicle's windshield, improving the driver's visibility and enhancing driving safety. 2. The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. The wiper motor uses a DC permanent magnet motor and is typically integrated with the worm gear mechanism installed on the front windshield. 3. The worm gear mechanism functions to reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into a left-right oscillating motion.

That hole actually leads to the drainage channel under the windshield. From what I remember after driving for so many years, rainwater or windshield washer fluid flows into the drainpipe there during rain or car washes, eventually draining under the car to prevent water from entering the engine compartment or the interior. If not cleaned regularly, leaves and debris can clog it, causing water to overflow onto the hood during heavy rain, leading to rusted components and even frying the circuit board. I’ve encountered this issue before—cleaning it was a hassle, and I had to spend money on repairs. So, while washing your car, take a moment to clear that hole to avoid a lot of trouble. Safe driving starts with small steps.

The hole at the base of the wiper is typically connected to the drainage channel at the bottom of the car, allowing rainwater from the windshield to flow away. As someone who frequently performs DIY car , I've noticed that if debris like fallen leaves or mud isn't cleared from the hole in time, the wiper may leak. In severe cases, water can accumulate under the car's chassis, leading to body rust. It's best to check it every quarter, flushing it with a hose to ensure it's clear. This also helps extend the wiper's lifespan. Don't wait for problems to arise—making it a habit saves a lot of hassle.

When I first got the new car, I was curious about what that hole was for. Later, I learned that it's directly connected to the drainage pipe under the car, allowing rainwater to drain out and preventing water accumulation inside. The design is quite , but it can easily get clogged, leading to leakage issues. I neglected it during my novice period, resulting in watermarks on the hood after rain. A simple regular maintenance routine is sufficient to prevent this.

The opening directly connects to the drainage system, allowing rainwater or washing liquid to flow out of the vehicle body. I commute on the highway every day. Once during rainy weather, the opening got clogged with leaves, causing water to backflow into the engine compartment and nearly damaging the electronic components. I rushed to the shop to get it cleaned, which solved the problem. Since then, I've been extra careful about keeping the opening clean, especially during seasonal changes, to avoid repair hassles and ensure driving safety.

The hole at the base of the wiper is primarily designed for drainage. Rainwater flows into the channel beneath the windshield and is then directed outside the vehicle through a pipe. The design incorporates leak-proof features to protect internal components. However, if left uncleaned for extended periods, accumulated dust and debris can clog the drainage hole, potentially causing water to overflow and affect the suspension or electrical systems. I've found that regular vacuuming can prevent such minor issues, ensuring the vehicle remains in good working condition.
