What Causes Water from Car Air Conditioning to Flow to the Passenger Seat?

[DeSavannah]

When water enters the car, it may flow to the passenger seat. Here are the detailed reasons: 1. Poor quality of drainage pipes: Some drainage pipes are of low quality, prone to aging and loosening, causing the pipes to bend and leading to poor drainage. Replace the drainage pipes promptly. 2. Loose installation of the air conditioning: Over time, the air conditioning may shift, causing the position of the drainage pipes to change and resulting in drainage difficulties. Condensation on the pipes may occur if the insulation material on the pipes is of poor quality or too thin, leading to condensation when refrigerant passes through. 3. Dirty heat exchanger requiring cleaning: If the filter is severely dirty or damaged and not cleaned in time, it can cause the evaporator to deform, preventing water from dripping into the tray in time. Insufficient Freon in the air conditioning system can cause the indoor unit's evaporator to freeze, preventing water droplets from dripping into the water-saving tray. Poor-quality materials or an unreasonable internal setup in the air conditioning system may prevent water from flowing into the tray, causing it to drip along the plastic shell.
