What is the reason for the sudden failure of car wipers?

[SiennaLynn]

Car wipers suddenly stop working due to motor damage, and replacing the motor can solve the problem. Wipers are blade-like structures installed in front of the windshield, consisting of components such as an electric motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Their primary function is to clear rain, snow, and dust from the windshield that obstructs visibility. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for wiper motors are relatively high, as they use DC permanent magnet motors. The wiper motor installed on the front windshield is typically integrated with the worm gear mechanical part.
