What Causes Noise in the Wiper Motor?

[VonJames]

Noise in the wiper motor may be caused by a connection failure in the transmission system, motor damage, or deformation of the wiper blade. Solutions: Check whether the connection between the wiper blade and the wiper transmission arm is secure, and whether there is any issue with the connection between the transmission arm and the motor. Remove the wiper blade and activate the wiper to see if the motor runs normally and if the transmission arm produces any abnormal noise. If problems persist, the motor may be damaged. If the motor and transmission arm operate normally without the blade, inspect the wiper blade for deformation. If the blade does not fit properly with the windshield, excessive friction may occur, preventing the motor from driving the blade smoothly and causing noise. Daily Maintenance: Purchase appropriate cleaning agents and regularly clean dirt from the wiper blades and residual grease from the windshield to ensure the wiper functions effectively. Replace the wiper blades after prolonged use to prevent aging and hardening due to weather conditions, which can lead to noise.
