What are the causes of water leakage from the co-pilot's air conditioner?

The main causes of water leakage from the co-pilot's air conditioner are the quality of the drain pipe, installation conditions, and the exchanger. Quality issues with the drain pipe: Some drain pipes are of poor quality, prone to aging and loosening, which causes the pipe to bend and results in poor drainage. Installation conditions: If the air conditioner is not installed securely, it may shift over time, causing the position of the drain pipe to change and leading to drainage difficulties. Condensation on the pipes. If the insulation material on the pipes is of poor quality or too thin, condensation can easily form when the refrigerant passes through. Exchanger issues: Severely dirty or damaged filters that are not cleaned or replaced in time can cause the evaporator to deform, preventing water from dripping into the tray properly. Insufficient Freon in the air conditioning system can cause the indoor unit's evaporator to freeze, preventing water droplets from dripping into the water collection tray. Poor-quality materials or an unreasonable internal setup in the air conditioner can prevent water from flowing into the tray, causing it to drip down the plastic casing. Pay attention to car air conditioner maintenance: The air conditioner is an essential part of driving and an important component inside the car. In winter, it is needed for warmth, and in summer, it is needed for cooling. However, if it is only used without proper maintenance, the air filter can easily breed bacteria over time, which not only harms human health but also reduces the car's lifespan.
Last time, my friend's car had a leaking air conditioner on the passenger side, soaking the entire floor mat and leaving a musty smell. Upon inspection, we found that the AC drain pipe was clogged with dust and leaves, causing the condensed water to accumulate inside the cabin. Similar issues are common in older cars, as the drain outlet is positioned low and easily collects debris. I've also seen cases where the pipe cracked due to aging or the evaporator seal failed, leading to leaks. Don’t underestimate this problem—accumulated water can corrode the car’s floorboard or wiring, potentially causing short circuits and serious issues. I recommend cleaning the drain pipe outlet every six months using a soft brush or wire to avoid costly repairs at the shop. Pay extra attention during humid weather, and spraying some cleaner through the vents can help prevent buildup. While a leak might seem minor, delaying repairs can lead to skyrocketing costs. Don’t compromise on safety when it comes to your vehicle.
