If the switch is faulty, it can only be replaced. If the electronic equipment doesn't work, it is common sense to check the fuse. Carefully check the fuse used in the power window.

2, motor overheating protection

In order to protect the power supply circuit, the general window lifting motor is equipped with overheating protection mechanism. If the components overheat for some reason, the motor will enter the overheating protection state, resulting in the failure of window lifting. In this case, just wait for the motor to cool down.

3. The guide rail is blocked or rubber strip is aging.

The window glass can't be lifted, mostly because it is stuck on the car body. We just need to clean the guide rail and apply some lubricating oil. If the fault is caused by the aging and deformation of the glass strip, we need to replace the new sealing strip. If it is too dirty, just clean it directly. Spraying some face wax on the glass sealing strip or smearing talcum powder (for lubrication) can play a good role.

4. The switch of the glass lifter is damaged.

The window up-and-down switch is a switch that is used very frequently in cars, and it will be used almost as long as you drive, so the probability of damage is also high. At this time, it is only necessary to directly replace the switch of the entire window regulator in the store.

Extended data

Maintenance of windows:

First, defogging the windows.

1, properly open the window, let the air inside and outside the car circulate, keep the temperature consistent, and avoid condensation on the inner surface of the windshield.

2. Turn on the air conditioner, adjust the temperature in the carriage and eliminate the fog on the windshield.

3. Once the fog beads condensed on the windshield affect the line of sight, don't wipe it while driving. Stop and wipe with a clean towel before driving.

4. Apply a thin layer of glycerin, alcohol or salt water on the windshield as an antifogging agent to prevent the inner surface of the windshield from fogging in a short time.

5. Pour a little detergent on the wet cloth and rub it evenly on the inside of the windshield, which can effectively keep it from fogging for 20 hours. When the weather clears or the line of sight improves, just wipe off the liquid film on the windshield with a clean wet towel.

Second, the power window fault and maintenance:

1, the reason why the electric switch window is not smooth is that the oil in the elevator inside the door is used up, so it is necessary to remove the oil on the inner cover.

2. If the glass can't move at all, it may be a switch failure. If the switch is faulty, it can only be replaced.

3. If the electronic equipment doesn't work, it is common sense to check the fuse. Carefully check the fuse used in the power window.

4. When the action of the switch becomes worse and the window cannot be opened smoothly, there is a great possibility that the switch will fail.

5. Before oiling the internal mechanism, first remove the inner cover. Remove the hidden screw and quick switch.

6. Remove the inner cover, peel off the plastic paper for waterproofing below, and expose the lifting mechanism of the window.

7. Spray grease on the inside of the arm fulcrum and gear. While moving up and down, spraying can make very small parts coated.

8. Sliders at both ends of the supporting glass also need to be inspected. When the sliding condition and heat conduction of glass are poor, it can be coated with brightener.

9. In order to make the glass slide smoothly, it is important to minimize the resistance. Glass pollution will also become resistance, so keep the windows clean.
