What to do if a business card falls into the car window

It is recommended to go to the garage to remove the door panel, otherwise it is easy to jam the glass lifter and block the drainage hole. But after many cars are dismantled, the connection between the door panel and the door is no longer so tight. In fact, if it’s just one, it usually doesn’t matter. Unless you are unlucky, the business card happens to block the drainage outlet, preventing the rainwater from draining out, which in turn causes rust inside the door and causes the automatic door lock to lose

What to do if a business card falls into the car window

It is recommended to go to the garage to remove the door panel, otherwise it is easy to jam the glass lifter and block the drainage hole. But after many cars are dismantled, the connection between the door panel and the door is no longer so tight.

In fact, if it’s just one, it generally doesn’t matter. Unless you are unlucky, the business card happens to block the drain outlet, preventing rainwater from draining out, which in turn causes rust inside the door and causes the automatic door lock to fail.

If you really want to take it out, go to a 4S shop or a professional auto repair shop and ask the mechanic to remove the door panel and take it out. Don't trust those tips online.

Attached is an introduction to automobile glass lifters:

Automobile glass lifters generally consist of the following parts: operating mechanism (rocker arm or electronic control system), transmission mechanism (gears, toothed plates) Or rack, gear soft shaft meshing mechanism), glass lifting mechanism (lifting arm, mobile bracket), glass support mechanism (glass bracket), stop spring, balance spring.

Working principle of electric glass lifter: Electric cross-arm glass lifter: It is composed of ordinary manual glass lifter, reversible DC motor and reducer. The working principle is to turn on the motor, which drives the reducer to output power, and moves the glass mounting bracket through the active arm and the driven arm or pulling the wire rope, thereby forcing the door and window glass to move straight up or down.

What to do if the car window cannot be raised

If the car window cannot be raised or lowered, the window lift switch may be faulty or the lift mechanism may be faulty. Check and replace the lifting mechanism or lifting switch.

For some older cars, it is normal for the windows to fail.

You can often see people giving away small business cards. These people will put the business cards in the gap of the lift glass of the car. The owner must take out these business cards before lifting the glass, otherwise the business cards will easily fall into the door.

If the business card falls into the door, it may be caught between the glass and the door, causing the glass to get stuck or the vertical speed to slow down. In severe cases, the glass cannot be lifted.

All doors have drainage holes. If the business card blocks the drainage hole, it will cause a more serious failure when it rains. So car enthusiasts need to pay attention to these small business cards stuck in the gaps of car windows.

If the car has been used for a long time and the windows are stuck up and down, and the vertical speed slows down, you can spray a little tape lubricant. After aging, the friction between the window seal strip and the glass will increase. Spraying a little strip lubricant can reduce the friction between the strip and the glass.
