Completed the overhaul of 4 doors. It took a long time because several malfunctions were found in each door.

For example, one of the doors was missing such a spiral spring.

As a result, the glass went up slowly, and when it came down, there were jerks. The spring is tricky; when the motor lowers the glass, it gets wound up. And when the glass goes up, as the spring unwinds, it helps the motor. Thus, the same speed for lowering and raising the glass is achieved.

I managed to find the spring, but I wanted to make a life hack and increased its initial winding so that the glass would go up faster.

wound it an additional 45 degrees.

The result inspired me, and I improved the same spring in the driver's door too. Now the windows go up very quickly. The electric motors are breathing easier now because they have a magical spring to help them.
