Nowadays, the configuration of the car is becoming more and more luxurious and classy enough. What constant speed cruising, self-parking, 360 °look, automatic headlights, wipers and so on, are so rich that the old drivers are at a loss, especially the panoramic skylight, the feeling of lying in the car looking at the stars through the glass is really cool!
You must be surprised if I say I won’t buy a car with panoramic skylights if I buy another car. There is no denying that the panoramic skylight is good or not, and it really makes you feel bad when something goes wrong. The rainy season is coming, and what I have experienced in the past few days has made me completely disappointed with the panoramic skylight. All right, let me take my time.
It is said that a few days ago, my brother and sister-in-law returned to the northeast from Yinchuan. I drove more than 100 kilometers to meet me at Harbin Taiping Airport. On my way back, I encountered heavy rain. The next day I found that there were water stains on the A-pillar of the car and infiltration of water under the co-driver’s feet. After inquiring, the heroes in the group told me that the sunroof drain was blocked, and told me that I bought a sharp weapon on a treasure that could pass through the drain. I worked out the front drain hole of the skylight step by step according to the instructions of my fellow motorists. There is a post as proof: do it yourself, solve the problem of sunroof drain blockage ~ https://www.xcar.com.cn/bbs/viewthread.php?tid=99273389
But, but, when I was going to tidy up the interior of the car, I found that there were also traces of water stains on the B and C pillars of the car, and this time it was my turn to look at a loss.

This is really fatal, the drainage hole in front of the skylight has just been dredged, how come there are traces of leakage in B-column and C-column? By communicating with the riders in the group, I know that the skylight has four drainage holes, two in the front and two in the back, that is to say, there is one in each of the four corners. But it will be troublesome if the drain hole behind the skylight is blocked, because the glass in front of the panoramic skylight is alive and moving backward can reveal the two drainage holes in front, while the glass behind the skylight is dead and can not reach the drain hole at all.
This is the infiltration mark on the roof behind the C-column.

This is troublesome. A car friend told me that if the drainage hole behind the skylight is blocked, it should be opened upwards from the exit hole under the car, so that the drainage hole behind the skylight can be opened.

But how can I find the location of the outlet under the car? The riders didn’t give the right answer either.
It seemed that I couldn’t handle it myself, so I threw the dredging artifact back from a treasure into the car and came to the 4S store. It happened that the masters were not busy and could solve my problem wholeheartedly.

I explained my friend’s idea with the master. The master said that the outlet under the car was on the exhaust pipe, and the exhaust pipe had to be removed before it could be found. The master said that according to his judgment, it was not necessarily blocked. It is very likely that the connection of the drainage pipe has fallen off or there is a gap leading to water infiltration. To remove the side board of the trunk to find the drainage pipe to re-glue firmly, so, according to the master’s idea went on.
Let’s start by removing the cover of the trunk.

It was a little difficult, and the horizontal ridge under the back door was also removed.

The buckle is a little too much, so I can’t pull it off without a little effort.

Some places are stuck, so that the strength can come down, in some places there are screws, and there is nothing you can do without pulling the wrench.

The wrench on the side was lifted, and there were a lot of electronic components inside. My Harvard H7 was really complicated, and it was the first time I had a chance to see the inside of the side of the trunk.

Curious, I asked the master about the role of these components. The master told me that the one like the circuit board is the rear electrical insurance, and the other box is the power amplifier module of the stereo.
The timbre of this Yanfei Lish stereo is really good!

The side panel was taken apart so that the roof could be pried.

I found the joint of the drain pipe, but it didn’t fall off, and the master pulled it out, glued it again and pushed it back. This is really technical work.

All right, after the pipe is glued, let’s put the board back. At this time, I think what the master said can not be blocked, which is reasonable, because the drainage pipe has a big mother’s finger thick, under normal circumstances can not be blocked at all.

The master is very rigorous in his work, and he needs to be careful to find and install a buckle. He likes the spirit and attitude of being responsible for the car owner.

The rainy season is coming, card friends must pay attention! In particular, the drainage hole of this skylight should be dredged regularly. Once it is blocked, water will flow into the light car, the car will smell moldy if it is not handled properly, and if it is serious, it will burn the electronic components in the car. In my case, a car friend reminded me not to let the blisters take too long. If the 360 °look module under my feet burns, it will cost at least 1500 yuan. Hey, from then on I made up my mind not to buy a car with panoramic skylights, or even one with skylights.

Through this lesson, I also feel that it is necessary to change the habit of using the car again. We should not just know whether to drive or not to maintain. Before the arrival of the rainy season, we should clear and clean the drainage pipes of the car, such as the sunroof drain hole, the front machine cover drainage hole, the trunk drain hole, the car door drain hole, the fuel tank cover drain hole, etc., especially the skylight drainage hole, which is most likely to clog and fall off and leak, resulting in irreversible consequences. All right, let’s learn a lesson and learn a lesson. May everyone’s road to using a car be smooth!
