What Causes the Wiper to Make Abnormal Noises?
2 Answers
The abnormal noise from the wiper indicates a malfunction in the wiper system. Below is an analysis of the causes and solutions for wiper noise: Specific causes: When the wiper makes abnormal noises, it usually signifies an abnormality or malfunction in the corresponding part, leading to issues such as the wiper not working, intermittent operation, continuous operation without stopping, or failure to reset. Solutions: After the wiper sweeps one or two times, observe whether any scratches are left and check if there is moisture remaining on the windshield. If these signs are clearly visible, it indicates that the rubber blade of the wiper has aged and should be replaced with a new one. If the wiper has been used for an extended period, it is recommended to replace it promptly.
I've got plenty of experience with noisy wipers. Last time during a heavy rainstorm on the highway, the sound was like fingernails on a chalkboard - absolutely spine-chilling. The key is identifying the type of noise: if it's a squeaking sound, it's most likely due to hardened wiper rubber blades losing their elasticity, essentially like scraping glass with hard plastic; a grinding noise often means loose wiper arm springs preventing proper blade contact; the most annoying is that clicking sound indicating rusted wiper linkage. Once I noticed wiper chatter with water streaks - turned out to be an oil film on the windshield. The solution is simple: thoroughly clean the glass with dish soap, inspect blades for cracks, and lubricate wiper arm joints with a few drops of engine oil. Never delay repairs - my colleague once waited too long to replace his and ended up scratching his windshield badly.
