Vision air conditioning water drain outlet is located in front of the front passenger seat, and the drain pipe is on the frame. Function of the air conditioning drain pipe: It is used to discharge the condensed water generated during air conditioning operation. When the air conditioner is cooling, a large amount of water droplets, called condensed water, are produced during the heat exchange of the indoor evaporator. A drain pipe is connected to discharge the indoor condensed water to the outside. Automobile air conditioning system: The automobile air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the compartment. It can provide a comfortable riding environment for passengers, reduce the driver's fatigue intensity, and improve driving safety.

I've been repairing cars for over a decade and often help owners with such issues. The air conditioning drain outlet of the Vision is located under the chassis right below the front passenger seat, with the black rubber tube's end being the exit. During summer cooling, condensed water from the evaporator is discharged here. If you notice the front passenger floor mat is soaking wet, there's an 80% chance the drain tube is clogged. It's recommended to check it every six months, especially for cars frequently parked under trees, as willow catkins and leaves easily block the tube opening. Cleaning it yourself is simple: use an air compressor gun to blow into the tube opening a few times, or insert a thin flexible tube to poke through. Never neglect this, as poor drainage can lead to moldy odors in the AC system and, in severe cases, corrode the chassis wiring harness.

A while ago, there was always water accumulating in the front passenger seat of my car. It took me quite some time to figure out the location of the drain hole. It's right near the chassis, behind the front wheels. If you squat down, you can see a small black funnel-shaped rubber . This spot is particularly prone to dust buildup. I used a bicycle brake cable to poke through it a few times, and suddenly about half a basin of water gushed out. Later, I learned my lesson and now I lift the floor mat every month to check if the carpet is wet. If you're doing this yourself, remember to stabilize the car properly with a jack and wear gloves to protect your hands. After clearing the tube, turn on the AC and observe the ground. If you see water dripping out, it means the drain is clear. This method works every time.

Simply put, the drainage outlet of the Vista is located under the chassis on the passenger side, appearing as a small black rubber head. If you're handling it yourself, it's best to choose a sunny day, park the car on a slope, and crawl underneath to spot it. Be gentle when clearing the tube, as aged rubber tubes can easily be punctured. My friend had a blockage last time, causing a musty smell inside the car, and spent over 200 yuan to replace the tube. For regular maintenance, keep two points in mind: first, avoid parking over piles of fallen leaves, and second, don't use a high-pressure water jet directly on this spot when washing the car. If you really can't find it, just go to a repair shop—the mechanic can fix it in five minutes.

As someone who has personally modified three cars, I have the authority to speak on this issue. The drain is located on the right side of the middle section of the chassis, with a diameter about the size of a pencil. The design principle is quite interesting: when the air conditioning is cooling, condensation forms on the evaporator, and the water droplets flow down the slope to this low-positioned outlet. My maintenance routine involves using the small nozzle of a vacuum cleaner to remove dust from the pipe opening, then gently clearing out any sludge with a thin wire hook. The key is to maintain the slope of the pipe. Last time, I saw someone install an underbody guard that flattened the tube, causing water to back up and flood the cabin. It's essential to check this part before the rainy season to save a significant amount on repairs.

My Vision hasn't had drainage issues in five years, and my secret is regular maintenance. Open the passenger door and look under the car - you'll see a roughly 3cm rubber tube extending near the chassis beam. The cleaning tools are super simple: wrap a cloth around a takeout chopstick, dip it in alcohol to clean the tube opening, then use a bicycle pump with a soft hose attachment to blow air through it. Last month I noticed slow drainage and discovered a gecko had made a nest inside. I recommend checking after car washes since high-pressure hoses can push debris into the tube. When doing this yourself, prepare a small basin to catch water and avoid wetting the garage floor.
