Usually, the power window system is equipped with two sets of control switches. The main switch is arranged on the dashboard or the driver's door armrest, and the driver controls the lifting of each window. The other set is installed on each passenger's door, which is a separate switch and can be operated by passengers. Generally speaking, the main switch is also equipped with a circuit breaker. If disconnected, the sub-switch will not work.

Precautions:
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.
