The wiper doesn't move, what's the matter?

If the wiper of the vehicle does not move, the common reasons are as follows:

1. There is a problem with the power supply of the wiper motor, which is usually caused by the damage of the wiper motor insurance, causing the wiper to not work normally;
2. The wiper motor itself is damaged, the motor itself is damaged or the control module integrated with the motor is damaged; after checking and confirming the damage, it can be replaced;
3. The mechanical structure connecting the wiper motor and the wiper arm falls off, which is not installed in place or damaged;
4. The wiper switch itself is damaged or its power supply grounding circuit is damaged;
5. There is a problem with the wiper motor circuit, such as an open circuit or short circuit in the power supply or negative circuit.

Possible reasons for a wiper not moving are:

1. The problem may be at high speed. There is a pressure plate on the wiper in front of the driver (itself is added force for cleaning). Due to the high speed, it is under pressure. At this time, the four-bar linkage mechanism cannot overcome the resistance temporarily. , resulting in inability to move, it's fine;

2. If it is still possible to move, it means that the motor is good, and the problem is not big. It is estimated that the screw is loose or there is some problem with the transmission. If you can't do it yourself, go to the repair shop to see it;

3. The wiper is also called a wiper blade, a wiper blade. When the wiper does not move or does not work, it can be dealt with in the following aspects: Pay attention to whether the way the strut is connected to the wiper rocker arm is correct. Because some of the arms are fixed to the rocker arm with screws, and some are locked with a convex buckle. Pull up the wiper and run your fingers to check for damage on the cleaned rubber wiper and the elasticity of the rubber blades. If the blades are aged, hardened or cracked, then the wiper is broken. During the test, put the wiper switch at various speed positions to check whether the wiper maintains a certain speed under different speeds.
