If one day, you open the car door and find that your car caused a flood. What can you do except panic? Where did this water come from? A series of problems need to be solved urgently. The car turned into a pond? Yes, the "catastrophic disaster" in which a carriage turns into a pond mostly happens in rainy days;
To sum up, there are probably the following reasons. Waterproof and soundproof strips at the door are seriously aging. The aging of waterproof strips basically occurs on old models. It is obvious that the owners can see the water leak. Obviously, it is enough to replace the waterproof and soundproof strips later.
Skylight leaks
80% car owners will ignore the maintenance of skylights. There will be a drainage trough at the skylight to guide rainwater from the roof to the bottom of the car. If it is not cleaned for a long time, it will easily block the drainage trough. When it rains, the rain will seep into the car. In severe cases, the A-pillar will leak water and there will be water marks near the skylight. Car owners can also try to clean the skylight when washing the car.
The water tank leaks, and the warm air of the car air conditioner depends on the engine coolant. Once the hot water tank in the air conditioner leaks, the coolant in the car will flow into the cockpit mercilessly, and the pond mode will be officially opened. When you find that the chassis of your car is all wet and there is little or no coolant in the water tank, you can conclude that the air conditioning warm water tank is leaking.
Will I be stingy with the solution to the intractable diseases I have worked so hard to find out? One of the most economical ways is to abandon the warm air mode, skip the warm water tank and connect the warm water pipes into a loop. Do you think it's simple and economical? Overhaul the air conditioner in normal maintenance mode, remove the air conditioner blower hidden under the dashboard and replace the warm water tank, which requires disassembling the entire dashboard;
The maintenance cost is relatively high. When the car starts the pond mode, there is too much water in the compartment, so it is less likely to air dry naturally. The key is to solve it as soon as possible, otherwise it will be moldy and smelly after a long time. There is more rain in summer, so take care of your car, start with the details, and don't ignore the small details.
