Why Won't the Windshield Wiper Move?

[LeMatteo]

Windshield wiper failure to move is caused by a loose motor connection. Below are relevant details about windshield wipers: 1. Operating Principle: The power source of the wiper comes from the motor, which serves as the core component of the entire wiper system. The quality requirements for wiper motors are exceptionally high. They typically use DC permanent magnet motors, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical assembly. The worm gear mechanism functions to reduce speed while increasing torque, with its output shaft driving a four-bar linkage mechanism that converts continuous rotational motion into oscillating side-to-side movement. 2. Basic Overview: This refers to the blade structure installed in front of the windshield, composed of the motor, reducer, four-bar linkage mechanism, wiper arm spindle, and wiper blade assembly. Its primary function is to clear rain, snow, and dust from the windshield that obstruct visibility.
