Car air conditioning drain holes are generally located under the chassis. Here are the specific details: 1. Air conditioning drain pipe: The car air conditioning drain pipe is positioned below the evaporator, connecting the evaporator to the chassis. During air conditioning operation, the evaporator continuously absorbs moisture from the surrounding air during heat exchange, which is then discharged through the drain hole. This explains why a puddle of water often forms under the car after the air conditioning has been running for a while. 2. Clogged drain pipe: If the drain pipe leading outside is blocked intentionally or by debris, condensation water cannot drain properly. Check whether the drain pipe is clear and whether it is properly connected to the air conditioning pipe. 3. Poor drainage: Long-term use may cause the drain pipe to age, loosen, or bend into a wavy shape, leading to poor drainage and partial blockages. In such cases, replacing the drain pipe is necessary to resolve the issue.

I've been driving for over a decade and have encountered the issue of air conditioning water dripping into the car several times. That drain outlet is usually located under the front passenger seat, to be precise, on the car chassis near the middle-right area. The water is condensed during air conditioning cooling and discharged through a small tube. If it gets clogged, water can flow back into the car, soaking the carpet and even causing a musty smell, which isn't good for health. Last time, I cleaned it myself by lying down and using an iron wire to unclog it. I recommend that beginners also check this spot regularly, especially during summer when the air conditioning is used more frequently. Remember, the exact position might vary slightly depending on the car model, but it's generally under the front passenger seat - just crouch down and you'll see it. This small detail might seem minor, but it actually affects comfort and hygiene quite a bit.

As an enthusiast who frequently tinkers with car interiors, I know from experience that the air conditioning condensate needs to be drained. The drain outlet is commonly located on the front undercarriage of the vehicle, positioned beneath the passenger seat or near the wheel area, aligned with the opening of the evaporator box. The water is a byproduct of the cooling process and must be expelled outside the vehicle to prevent accumulation or corrosion of parts. I've found that if it gets clogged, it can cause water leakage into the cabin, leading to mold issues or affecting other electronic wiring. In daily maintenance, I simply bend down every three months to visually inspect the location and use a soft tube to gently blow air for testing. This kind of maintenance doesn't require professional tools but is crucial for protecting the interior environment. The location is easy to find—just crouch down and you'll see the small pipe. Keeping it clear ensures the air conditioning runs longer and more reliably.

As a new driver, I just learned that the air conditioning drain hole is located under the passenger seat on the vehicle chassis - you have to crouch down to see it. The water is condensation produced during AC operation. If clogged, it can leak into the cabin, making seats wet and smelly. Checking it's easy - just lie down and use phone flashlight. The manual says this spot is easy to locate but warns against poking it hard during cleaning. For prevention, I always check if it's clear after each car wash. Such small things can't be ignored - timely maintenance prevents bigger issues.
