What should Nissan hacker do if the skylight drain hole is blocked?

Summer is a long test for cars-not only exposure to the sun, but also stormy weather.

Especially in rainy months, there will be a heavy rain every once in a while. If you don't pay more attention, the skylight of the car is easy to damage or even leak rain.

In order to avoid this situation, today Tian has compiled some tips for maintaining skylights for everyone. Let's go and have a look!

Skylight structure and drainage principle

Before doing skylight maintenance, we must first understand the structure of skylight.

There are two sliding rails on the left and right sides of the skylight to ensure that the skylight slides back and forth. At the left and right corners of the front of the slide rail, there are drainage holes of the skylight, and there is a water guide channel between the two drainage holes.

After the rainwater hits the skylight, it will first flow into the waterway and then pass through the drainage holes on both sides. The drainage hole is connected with the drainage pipe, and the drainage pipe passes through the A-pillar of the automobile. The rainwater is guided to the fender of the front tire by the drainage pipe, and then discharged. Of course, there are also water outlets on both sides behind the skylight, from which rainwater will be discharged from the C-pillar of the car.

(common sense: when it rains or washes the car, it is found that water drops fall into the water guide trough and flow out of the car through the drain hole and drain pipe. It is normal for water to drop in the water guide tank; For example, after the drain hole and drain pipe are blocked, the water in the water guide tank can't be discharged, which causes the water in the water guide tank to disperse and the skylight to leak, so it is necessary to regularly confirm whether the drain pipe and drain hole of the skylight are blocked)

How to deal with the skylight failure?

There are two common skylight problems.

? When the drain pipe is blocked or broken, water will seep from the skylight and drip into the room. If it is broken, it will also cause water seepage in the A-pillar and C-pillar of the car.

? Sunroof sealing strip is aging, resulting in water seepage in the skylight.

1 drain pipe is blocked.

If the skylight seam is found to be leaking, it is probably because the drain is blocked. If the original drainage hole of the vehicle is designed to be small, then a little impurity or sediment will easily block it.

In this case, you can find a thin wire or bicycle brake line and poke it in with this soft and tough wire to dredge it. After dredging, you can use mineral water to fill the diversion trough, and try to see if the water can flow out of the fender of the front tire. If so, it's a success.

No.2 drain pipe or sealing strip is aged and damaged.

If the A-pillar or C-pillar of the vehicle is found to be leaking, it is likely that the skylight outlet or connector is broken. This situation is very complicated, and it may be necessary to remove the interior and replace it with a new drainage hose. This project is a bit big. In order to avoid trouble, you can drive your car to Geely authorized service station for replacement.

In addition to the problem of the drain pipe, the rubber sealing strip on the edge of the skylight is also very easy to age or crack, resulting in poor sealing and water seepage of the skylight. If rubber strip is damaged or leaked, it can only be replaced at Geely authorized service station.

Matters needing attention in daily maintenance of skylight

In order to better protect the skylight, Youbao has also compiled a set of super practical skylight maintenance cheats for everyone. You are welcome to take them!

1. Pay attention to the waterproof performance of the skylight.

The skylight is sealed by a rubber sealing ring around the window glass. Pay attention to the dust prevention of the sealing ring during use, especially after winter or long-distance driving, and clean it with a duster.

In addition, it must be noted that the sunroof cannot be forcibly opened when it freezes, which will damage the motor of the sunroof.

2. If necessary, close the sunroof.

When driving on bumpy roads, it is recommended not to completely open the skylight, otherwise the vibration between the skylight and the slide rail will be too large, causing deformation and abnormal noise of related components and even damaging the motor.

3. Pay attention to tightness.

In the cleaning process, avoid washing the sealing ring around the skylight glass directly with the water column of the high-pressure water gun, so as to avoid the deformation of the sealing ring under the impact of the high-pressure water column and cause water to enter the car.

4. Pay attention to lubrication and anticorrosion maintenance.

During the daily use of the vehicle, the track and sealing ring of the skylight should be cleaned regularly. If you hear a creaking sound when opening the skylight, it may be that the lubricant of the slide rail is gone or the lubrication is poor. You can ask the service station to help you repaint the special skylight guide rail grease for lubrication.

Use neutral detergent

Before opening the skylight, you should pay attention to whether there are obstacles on the roof that hinder the operation of the skylight glass. If there are obstacles, please clean them with a soft cloth and neutral detergent, and do not use sticky detergent.

Clean up foreign objects and keep them clean.

In rainy summer, always check whether there are foreign bodies such as sand and leaves in the water guide tank in front of the skylight, and regularly wipe the water guide tank with a clean wet towel to prevent the skylight drainage hole from being blocked.
