Why does the car drip water when the heater is on?

[DeLila]

The reasons why a car drips water when the heater is on: 1. Metal pipes may leak due to rust, welding cracks, or vibration cracks, and the only solution is replacement; 2. Rubber pipes may leak due to poor temperature resistance or pulse pressure resistance, and replacement is also necessary; 3. Leakage at the connection between metal pipes and rubber pipes may require replacing the clamp or reinstalling and adjusting it. Car heating relies on the engine's heat. When the car's heater is on, the high-temperature antifreeze in the engine flows through the heater core. At this time, the air blown by the blower may also pass through the heater core, allowing warm air to be blown out from the car's air vents.
