2. The picture above shows the position of the co-pilot foot pad. When you see water with obvious rust color, since it is a problem with the warm air tank, you should get rid of it. However, this heating trough is not easy to disassemble, so the instrument panel must be disassembled first.
3. The above picture shows the removed instrument panel, which is removed as a whole. One of the most common problems in the disassembly and assembly of instrument panel is that there will be more small screws after installation. We saw that the co-pilot of this car had no airbag.
4. The picture above shows the removed heater water tank. You can see rusty water flowing down from the ground, and there are many above and below. The root cause of water leakage is the corrosion of the warm air tank, and the root cause of the corrosion of the warm air tank is that the owner does not use antifreeze in spring, summer and autumn, but uses water, and the water is very corrosive, which will cause corrosion damage to the warm air tank after a long time.
Matters needing attention in expanding data to prevent drainage hole blockage;
1, pay attention to clean up the sundries and dust near the drain hole every time you wash and maintain the car.
2. Try to avoid direct drainage holes when washing cars independently.
3. It is best to park the car in a cool place to prevent the direct sunlight from slowing down the aging of rubber parts and causing the gap to become larger.
4. For vehicles with skylight, it is very important to check the sewer pipe of skylight. If the sewer pipe is blocked, it will cause the co-pilot to leak water after washing the car or in rainy days.
5. For vehicles without skylights, it is very important to check the air duct of the air conditioner, and the blockage of the drainage hole of the air duct will also cause water leakage.
6. There is a gap at the front joint of the co-pilot, resulting in water leakage.
