Why is the water from the car air conditioner flowing into the car?

[EvangelineAnn]

The reason water from the car air conditioner flows into the car is due to a clogged air conditioner drain pipe. Common causes of clogging: 1. Incorrect installation: After disassembling and reassembling the dashboard at a repair shop, the drain pipe may be installed incorrectly, causing water to flow into the car. A common symptom is water stains on the right front floor mat. 2. Evaporator coil blockage: If it's a new car, the evaporator coil may be internally clogged, or the drain outlet of the evaporator coil may not have been properly treated during manufacturing (a rubber film at the drain outlet prevents water from draining). 3. Drain pipe detachment: Another possibility is that the rubber drain pipe connected to the evaporator coil's drain outlet has come loose or is not properly secured.
