Why Won't the Wuling Sunshine Wiper Move?

[DelBrooke]

Wuling Sunshine wiper may not move due to residue on the wiper, which can be cleaned before trying again. Here is some relevant knowledge about wipers: Wiper Operation Principle: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives the four-bar linkage, which converts continuous rotational motion into left-right swinging motion. Wiper Function: It is a tool on the front glass of motor vehicles used for simple cleaning to prevent rainwater and other debris from obstructing the view.
