Types of failure of LaSega window rising button and ultimate repair practice (attached to the magic method for removing skin coatings)
AugusHoyle 
9 My 08 hatchback automatic fashion version Sega has accompanied me through the 13th year of my life, and the longest confession in life is companionship.
I get sicker as I get older, and my Sega and I are witnessing the process together. The driver’s seat lift window has been out of order for many years, and now I am really worried about the hospital, so I take advantage of the National Day to operate and operate myself!
The fault has been repaired on and off for many years, which is also the evolution of the idea of repair, and the repair of different types of faults has been practiced, which is summarized as follows:
1. Failure phenomenon: the two window buttons in the back row gradually fail at the same time, but the glass is raised and lowered as usual with the keys from the back door.
2. Repair process: an is first wiped with anhydrous alcohol to remove the oxide layer, which is almost ineffective
B then consider the physical deformation, the key is not in place to cause failure, so hand-made two “boots” for the button (attached to the picture) to increase the effective stroke of the key, after twists and turns invalid!
C finally, it is also the final judgment, perhaps it is the circuit problem related to the back window of the circuit board, according to this train of thought, it is found that it is a virtual welding problem, and the fault has been satisfactorily solved. The detailed process is attached.
D rear window lock key shrapnel gap is too large, the two shrapnel involved will be slightly bent to reduce the gap between the shrapnel and the contact after perfect repair.
All the repair methods of the window keys are nothing more than the above 4 points, in fact, the repair of other models is the same.
3. Appearance repair: skin-like removal operation.

Don’t say much, open it!
The first two times these contacts were wiped with anhydrous ethanol, or even polished with fine sandpaper, which is also the solution to most of these problems, which can generally be solved by key failure caused by contact oxidation, but this is not my problem.
After repeated testing and observation, it is found that the function of the key can be temporarily restored by pressing the wire harness joint and its surroundings with your hands, so it is the problem that the key contact is not in place caused by physical aging and deformation, so the second solution is started. Do it yourself to “raise” the button leg.
This is what the button looks like after putting on a special “boot”, but frustratingly, it still hasn’t solved the problem.
The final plan: check the circuit board, combined with only the rear window button failure phenomenon, focus on the rear window terminal post, but the old eyes are dim, can not see why, simply turn out the electric iron hidden in the snow for many years, simple and rough is the most effective!
Try to repair the welding directly! To make the solder firm, adjust the temperature to 400 °C and weld all three pins. The installation test was unexpectedly successful!
The above three types should cover most of these failures, so this post is called “ultimate”.
I have also searched the Internet many times, and the solution is alcohol. This time, I sum up my experience and hope that the newcomers will take fewer detours.

Let’s go to the appearance treatment stage to remove the skin!
Idea: organic solvent + abrasive
Wind oil essence, safflower oil, bone water. Things like volatile scents are rich in aromatic hydrocarbons and are good organic solvents. And toothpaste is rich in very fine advanced abrasives, directly polished with coarse cotton cloth, the result is too hard!

The black paint in these places has fallen off, in fact, there are aromatic substances in toothpaste, there is no need to use wind oil essence, safflower oil and so on. A lesson! Let’s spray some black paint later.
This rearview mirror folding selector switch is broken. I bought one from a treasure Sanshui home, which is obviously different, but online merchants all mark this as Sega’s exclusive use. I think I should use the other one labeled as Elysee. I guess this will work, too. I’ll make do with it.
Do it yourself and save dozens of dollars, if to 4S it is estimated to be hundreds of it, knowledge is money ah! Thinking of the experience of not studying hard at school, I finally understand why I didn’t become a millionaire!
Although it takes 7-8 hours to repair the failure of your car, the joy of the result is priceless, and the happiness of life is actually quite easy to achieve.

Add: after installation, it is found that the lock key to control the rear window (as shown in the picture) is out of order, and after observation, it is found that the shrapnel gap after pressing the button is not connected.
Use a pair of tweezers to carefully bend the shrapnel as shown on the right to reduce the gap and repair it perfectly after installation and testing.
This should be another repair method: shrapnel gap adjustment.
