Why is the car air conditioning cooling but not draining water?

[VivianDella]

Car air conditioning cooling without drainage may be due to a blocked drain hole, resulting in poor cooling effect. Additional information: 1. Inspection method: Check if the air conditioning drain hole is blocked; Lift the floor mat to see if there is water accumulation under the passenger seat; Use a thermometer to measure the air outlet temperature to see if it is normal. 2. Common causes of blockage: After disassembling and reassembling the dashboard at a repair shop, the drain pipe may not be installed correctly, causing water to flow into the car, with the common symptom being water marks on the carpet. If it is a new car, the evaporator core may be internally blocked, or the drain outlet of the evaporator core may not have been properly treated during production; The connection between the drain outlet of the evaporator core and the rubber drain pipe may have come loose or is not properly connected. 3. Solution: If you encounter the problem of the air conditioning not draining, immediately go to a 4S shop or repair point to find a professional technician to handle it.
