The main reasons for this leak are the following:
First, the skylight drain hole is blocked. Uncleaned for long periods of time, miscellaneous items such as dust, leaves and so forth are concentrated in drains, resulting in congestion. Leakage occurs when the sink is overstretched。
Second, the skylight seal is old and broken. As the mileage of vehicles increases, rubber products such as seals are ageing, and the surface is hardened, creating cracks, resulting in reduced sealing performance and water leaking into the vehicle。
Finally, the skylight drain fell off. On a rainy day, water from the ceiling skylight enters the drain pipe through the drain, and if it drops, it flows into the vehicle along column a。
The following measures could be taken to address the problem of leaking skylights:
In the case of congestion, drainage holes need to be clogged. If the vehicle is not covered by quality assurance, the owner is required to process it at his own expense to shop 4s, at a cost of between $300 and $500, and at a maintenance shop, at a cost of between $200 and $300。
For ageing and broken seals, the seals need to be replaced. After the vehicle exceeded the quality assurance period, the cost of replacing the 4s store was between $500 and $800, while the cost of the maintenance shop was around $500。
If the drain is to fall, it will need to be re-established. After the vehicles exceeded the quality assurance period, the cost of the 4s shop was between $300 and $500, while the cost of the maintenance shop was around $300。
In the area of routine maintenance, care should be taken to regularly clear the skylights and maintain the perimeter of the drainage tanks. When washing a car, special equipment for high-pressure spraying can be used to spray in the direction of the drain pipe in order to clean up the contamination in the pipe. If there is a “lifting” shift in the seal, plastic protective agents or slide powder may be sprayed on the seal to reduce friction. When using the skylight, if it is found that it is not close, it is possible to tilt the back of the skylight and hold the switch for one minute, making it completely closed. To develop the right usage habits to avoid the complete opening of the skylight in the face of the road, to prevent the parts from deforming or damaging the electrical apparatus, and not to mismanage the locks or twists of the manual skylight。
