Car wipers are very important for drivers in driving , providing a bright view . When a failure occurs, it has a very large impact on the driver’ s driving safety . There are many reasons for the failure of the car wiper power from the source of the car wiper power .

 

 

The following two types of faults have a higher probability of occurrence :

 

 

1. Motor failure

 

 

Usually sent directly to the factory for repair, or replace it with a new one. Due to the complexity of the motor mechanism, it is not recommended for the driver to repair it himself .

 

 

 

2. Transmission line failure

 

 

There are two types , which are short circuit and open circuit .

In actual repairs , it is basically because the switch is broken, or the contact is poor , so the fault is carefully analyzed .

 

 

 

And what is the reason why the wiper is not clean  ?

 

1. The wiper blade has failed .
2. The wiper arm is too loose .
3. The glass water purifier is faulty .

 

 

Six points to purchase :

 

 

First : Figure out which type of wiper blade you are using for your car. Refer to the car manual for the type of wiper indicated above .

 

 

Second: Pay attention to whether the way the pole is connected to the wiper arm is matched, because some of the arms are fixed to the rocker with screws, so be careful when buying .

 

 

 

Third: Check the rubber of the wiper. Use your fingers to touch the new wiper rubber to see if there is any hand or damage. Also, bend the rubber piece and test the elasticity of the rubber material. If rubber Surface damage, cracks do not meet the standard, is a poor quality wiper .

 

 

 

Fourth : During the test, place the wiper switch at various speed positions to check whether the wiper maintains a certain speed at different speeds. Especially in the intermittent working state, it is also necessary to pay attention to whether the wiper blade maintains a certain speed during the movement .

 

 

 

Fifth : Check the state of the wiper and whether the wiper strut has uneven swing or slip. If the following three conditions occur, the wiper blade is unqualified. The swing is not smooth and the wiper does not move normally. The contact surface of the rubber and the glass surface cannot be completely adhered to each other, resulting in wiping residue. After wiping, the glass surface is in a state of water film, and fine streaks , fog and linear residue are generated on the glass .

 

 

 

Sixth : When testing the wiper motor, it should be noted that the wiper motor has abnormal noise during operation, or there is corrosion and jam. If the wiper motor has the above conditions and does not operate, the wiper switch should be turned off immediately . To avoid burning the motor. This type of wiper motor does not meet the standard and is not included in the selection .
