What is the reason for the wiper still moving when turned off?
1 Answers
Wiper still moving when turned off is caused by poor line contact, and this situation can be resolved by having maintenance personnel reconnect the lines. The wiper refers to the blade structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. Its main function is to remove rain, snow, and dust that obstruct the view on the windshield. 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, as it is a DC permanent magnet motor. The wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part.
