I believe that many friends have encountered that once they encounter a car wash or rainy day, there will be water leakage and water accumulation under the feet and roof of the car. So, what is the cause of the water accumulation and leakage in the car? And how should it be solved? Let's take a look!
First, the sunroof drainage hole is caused by the blockage, which is also the most common cause of failure of models with sunroof configuration. In the treatment, you can find the drainage hole by opening the skylight, and then use the high-pressure air gun or wire to dredge it, and finally recommend that the riders clean up the water in the car in time to avoid corrosion of the computer version of the module and line pins due to long-term deposition. In addition, in addition to the blockage of the skylight drain will cause water leakage, if the skylight guide pipe falls off, it will also cause water leakage and water accumulation in the car. During processing, the trim panels on the left and right sides of the instrument panel A column can be removed separately and re-fixed by hand. If the gap in the water pipe interface becomes larger, the catheter can be baked with a lighter or heating gun before installation.
The second is the damage to the warm water box under the dashboard in the car, resulting in antifreeze leaking into the car, so this stagnant water is essentially a cooling antifreeze. In the processing, you can open the hood of the vehicle, check whether the coolant is sufficient when the cold car is running, if not enough, it is the water caused by the coolant leaking into the cab, and the solution is to replace the warm water box. If it is not treated for a long time, the vehicle may also have high water temperature, no warm air and other fault phenomena. Therefore, it is recommended that all riders find faults and deal with them in time, so as not to increase high maintenance costs until the end.
Third, the air conditioning drain pipe on the evaporation box under the instrument table in the car is blocked or detached, and the air conditioning drain pipe is blocked, which will cause the condensate to be discharged normally out of the car. In the processing can first start the vehicle and open the AC refrigeration switch, and then observe whether the ground has air conditioning water flowing out, if the ground is only a little or no, it is caused by the air conditioning drainage pipe blockage and shedding, only need to reinstall or dredge the drainage pipe to solve the problem.
Fourth, the body skeleton rust of the vehicle causes water from the outside of the car to enter the car, and for the problem of rust of the body skeleton, it can only be solved by removing the interior accessories and re-repairing and welding. Finally, if there is no problem with the above parts, then it is necessary to check whether the sealing strip of the door and rear tail door of the whole car is aging, whether the sealant under the windshield is invalid, if there is a problem with the sealing strip, it can be replaced; if the glass glue under the windshield fails, it is necessary to remove the glass and re-glue it to solve.
The above are the most common causes and solutions for water accumulation and leakage in the car, namely the blockage of the sunroof water pipe, the leakage of the warm water and water tank, the blockage of the drain pipe of the evaporation box, the corrosion of the body skeleton and the damage of the sealing strip. I hope to help you and reduce the troubles of daily use of cars and car maintenance!
