Front wiper motor not working.
Reasons for the front wiper motor not working may include:
The wiper screw is loose: Check and tighten the wiper screw.
Damaged wiper blade: If the wiper blade is seriously damaged, it needs to be replaced in time.
Wiper motor damage: The motor is the core of the wiper system, if the motor is damaged, the wiper will lose its power source.
Blown fuse: Check whether the fuse is intact. If it is blown, replace it.
Transmission connecting rod dislocation: Open the lead cover to see if the transmission connecting rod dislocation, which is one of the common reasons.
The wiper switch, circuit, and direction indicator combination switch are damaged: Check and replace the damaged switch or circuit.
Wiper circuit fault: Check whether there is a short circuit or open circuit.
The mechanical structure of the middle connection between the wiper motor and the wiper arm falls off: it is not installed in place or damaged, and needs to be fixed to the correct position or replaced.
Solutions to the non-working of the front wiper motor include, but are not limited to:
Tighten or replace wiper screws and wiper blades.
Replace damaged wiper motor or fuse.
Repair or replace damaged wiper switches, line and direction light combination switches.
Check and repair short circuit or open circuit problems in wiper lines.
Adjust or replace the falling mechanical structure.
When performing the above operations, if you are not familiar with or confident, it is recommended to seek professional help to avoid causing more damage.
Wiper's not moving in first gear, second gear, third gear
If the wiper does not move in first gear, and the second and third gears can be moved, it indicates that the internal switch of the wiper combination handle is in poor contact, or the resistance mode of the wiper is broken. Because the three modes of the wiper are achieved through the switch to control different resistors, if the switch or resistance is broken, some of the gear will not respond, at this time, you need to check the internal switch or replace the motor of the wiper after maintenance to restore the function of the wiper.
If the car's wiper is damaged, it needs to be repaired in time to avoid the failure of the wiper, affecting the owner's use of the vehicle. The function of the car wiper is very important, especially when it rains, if the wiper can not be used, the driver's vision will become blurred, which will increase the safety risks, be sure to repair the vehicle's wiper, and then use the vehicle to travel.
What are the parts of the wiper motor
1. Motor body
The motor body of the wiper motor is composed of two types of permanent magnet motor and AC induction motor, of which the permanent magnet motor has the characteristics of small size, light weight and fast response speed, while the AC induction motor has the advantage of simple structure and easy maintenance. The speed and output torque of the motor determine the wind effect of the wiper, so the body of the motor is the most important part of the entire wiper motor.
Two, reducer
The reducer is the motor high-speed rotation into low-speed and high-torque output components, usually using gear drive, worm drive, gear - worm drive and other structures, the quality of the reducer is directly related to the wiper operation effect and life.
Three, circuit board
The circuit board is the control center of the wiper motor, including a motor driver, which can control the speed and direction of the motor, and control the motor speed, starting current and rated current and other parameters to ensure the normal operation and service life of the motor.
Four, the wiper arm
Wiper arm is the part of the motor power transmission through the reducer, made of aluminum alloy, carbon steel and other materials, including the wiper arm skeleton, wiper blade and other parts, the quality of the wiper arm is directly related to the operating effect and noise level of the wiper, so special attention should be paid to the selection and installation.
In general, the wiper motor is an essential part of the vehicle, each component of which has a crucial role in the operation of the entire wiper. Therefore, when selecting and purchasing wiper motors, we should choose products with good performance and quality assurance according to our own models and actual needs.
