What's wrong with the car electric doors and windows not lifting?

Consider two faults: 1 electrical fault circuit fault 2 mechanical fault.

If you want to maintain your own maintenance experience, you can start from the first floor and check one by one. If it is a high-end car, I suggest you go to a repair shop with automobile maintenance qualification for maintenance. After all, it doesn't cost too much to repair high-end windows by ourselves, which will leave some hidden dangers that we can't solve by ourselves, such as airbag failure or other lines being broken or short-circuited. Generally, cars with long years will have the phenomenon that the windows can't be lifted and they have to go.

When the car is driving outdoors, sand and rain will enter the window, making the window rust along the rubber aging support rod, which is the most easily overlooked place when maintaining the car. If the rubber is aging and not smooth, it will fail to rise for a long time and burn out the motor. It is suggested to add plant essential oil or detergent to the automatic window, which can prolong the life of the window.
